This is a list and brief description of notable pipe organs in the world, with links to corresponding articles about them.

Historic organs

• It is generally agreed upon that the world's oldest playable pipe organ is located in the Basilica of Valère in Sion, Switzerland. Built around 1435, most of the case is original, but only 12 pipes are original, as the rest have been replaced during restorations.^[1]
• It is said that the organ in the church of St. Andreas at Ostönnen (Westfalia, Germany) is even older than the organ mentioned above. Its wind chests and divisions date back to 1425 - 1430, and half the pipes are still original. However, the case and key action were rebuilt in the Baroque period.^[1]
• In the San Petronio Basilica in Bologna there is a Lorenzo da Prato organ built in 1475 with a lot of original stops, and is still playable after a restoration took place in 1986.
• In the Old Cathedral (Duomo Vecchio) in Brescia (Italy) there is a Giangiacomo Antegnati (1536) - Fratelli Serassi (1826) organ. When in the 19th century the Antegnati was restored and enlarged, the priests of the church, in admiration of Antegnati masterpiece, asked Serassi to preserve all the old pipes.
• The organ in Évora Cathedral in Portugal was built in 1562. Some of the materials used belong to a previous instrument from 1544. This organ is fully functional today. It had interventions in 1694 by Heitor Lobo, 1760 by Pasquale Gaetano Oldovini and 1967 Dirk Andries Flentrop.
• In Wilhelmsburg Castle in Schmalkalden, Germany, there is a historic organ built between 1587 and 1589 by Daniel Meyer. Notably its facade pipes are veneered with ivory.

The Wood carvings on the facade were made by the German master carver Mårten Redtmer (dies 1655), he also worked on the royal warship Wasa.
• The Johann Woeckerl Organ in the Cathedral-Church of Saint-George in Sopron, Hungary, was built in 1633, but the pipes of its Holzflöte 8 stop were made in 1580. Among the church's congregation was Vitus "Veit" Bach, a miller whose great-great grandson Johann Sebastian Bach would compose the most celebrated organ music in the world.

The largest pipe organs in the world

There are many methodologies for comparison of organs according to their size. One of the most encompassing methodologies was described by Michał Szostak.^[4]

Civic and concert hall organs

Organ	Country	Location	Builder	Specifications	Details
Boardwalk Hall Auditorium Organ	United States	Boardwalk Hall Atlantic City, New Jersey	Midmer-Losh Organ Company, 1929-32	7 manuals 314 stops 449 ranks 33,451 pipes[5]	The largest pipe organ ever built, based on number of pipes. It weighs approximately 150 tons. Most of the organ has not functioned since 1944; a partial restoration in 1998 was largely reversed by construction damage during a renovation of the Boardwalk Hall shortly afterwards. Parts of the organ are again being restored to playing order in a $16M restoration effort that is expected to be completed by 2023. The Historic Organ Restoration Committee reports that as of 2018, 95% of the Ballroom Organ is operational, and 50% of the Main Auditorium organ is operational.[6] Restoration work is ongoing to the extent that public concerts have resumed.[7] It contains the world's largest Diaphone, the 64 ft Diaphone-Dulzian in the Pedal Right Division, which is also one of only two full-length 64 ft stops in the world, the other being the 64 ft Contra-Trombone stop at the Sydney Town Hall Grand Organ (See below)[8] The Grand Ophicleide (organ stop) in the Pedal Right Division, speaking on 100" wind pressure, is also recognised by The Guinness Book of World Records as the loudest organ stop in the world. It is described as having "a pure trumpet note of ear-splitting volume, more than six times the volume of the loudest locomotive whistle". In fact, the Grand Ophicleide produces 130 dB at 1 meter distance.[9]
Wanamaker Grand Court Organ	United States	Wanamaker's (Now Macy's Center City), Philadelphia, Pennsylvania	Los Angeles Art Organ Co., 1904 Wanamaker store Organ dept, 1914-17, 1924-30	6 manuals 376 stops 464 ranks 28,750 pipes	The largest pipe organ in the world, based on number of ranks and physical mass weight. It ranks second in the world based on number of pipes.[10] It is the largest fully operational musical instrument in the world, with the weight of 287 tons. This concert organ was initially constructed for the 1904 World's Fair in St. Louis; it was designed by George Ashdown Audsley. The organ was purchased by John Wanamaker for his palatial Philadelphia store; disassembled, the organ filled 13 rail cars. Uniquely, the Wanamaker Organ had from the beginning full-time organ fabricators and technicians, a true "organ shop", building it to luxurious standards of quality.[11] It is played twice a day, six days a week, and there are many recordings of this organ.[12] Its 88-rank String Organ is the largest division in any pipe organ in the largest single organ chamber. Its Pedal Organ of 75 ranks (supplemented by additional borrowed ranks) is the largest Pedal department of any instrument, possessing unsurpassed richness of tone with the capacity for subtle bass gradation in volume and complete separateness of musical line from the manual stops. At 71 ranks, its Swell Division is the largest Swell ever built. It is the largest organ built to a straight design with minimal resorting to unification. It has more expression pedals (10) than any other pipe organ, and 8 separately expressive pipe divisions. Despite its formidable size and power, its strength and hallmark is in musical subtlety and nuance. It is also recognized in the Guinness Book of World Records.
Auditorio Nacional (National Auditorium)	Mexico	Mexico City	Pontificia Fabbrica d'Organi Cav. Giovanni Tamburini CREMA - ITALIA	5 manuals 250 ranks 15,633 pipes[13]	The largest concert hall organ in the Western hemisphere and world's 6th largest concert hall organ (2nd and 7th respectively, if the Midmer-Losh in Boardwalk Hall is included).[14]
Newberry Memorial Organ	United States	Woolsey Hall, Yale University, New Haven, Connecticut	E. M. Skinner	4 manuals 142 stops 197 ranks 12,617 pipes	The largest fully operational concert hall organ in the US. It is the third largest fully operational concert hall organ in the world, behind Auditorio Nacional and the Sydney Opera House organ.[15]
Barry Norris Residence	United States	Birmingham, Alabama		5 manuals 161 stops 200 ranks 11,200 pipes	The world's largest house organ. It can be played from the console in the living room.[citation needed]
Curtis Organ	United States	Irvine Auditorium, University of Pennsylvania, Philadelphia, Pennsylvania	Austin Organ Company, Op. 1416, 1926	4 manuals 163 ranks 122 stops 10,731 pipes[16]	This organ was built for the Sesquicentennial Exposition in Philadelphia. At the time of its installation it was the fourth largest organ in the world. The presence of the Wanamaker Organ ranked it as the second largest pipe organ in Philadelphia. For many years it was ranked as 11th largest by pipe count, but recent combining of instruments under single console control have placed it in the top 25 largest in the world by ranks or pipe count.
Sydney Opera House Grand Organ	Australia	Sydney Opera House, Sydney		5 manuals 130 stops 207 ranks 10,888 pipes	The largest organ with mechanical key action.[17]
National Kaohsiung Center for the Arts Organ	Taiwan	Fengshan District, Kaohsiung	Johannes Klais Orgelbau	>9,000 pipes 105 stops 158 ranks	This is the largest organ in Asia.[18]
Sydney Town Hall Grand Organ	Australia	Sydney		5 manuals 127 stops 8,756 pipes[19]	This organ was for many years after its inception the largest in the world, and was the largest built in the nineteenth century.[20][21][22] It remains the world's largest organ without any electric action components and is one of only two organs with a full length 64 ft stop (the Contra-Trombone in the pedal) (click here for a sound sample).[23] (The other being the Boardwalk Hall Auditorium Organ.)
Fred J. Cooper Memorial Organ	United States	Kimmel Center for the Performing Arts, Philadelphia	Dobson Pipe Organ Builders, Op. 76	4 manuals 125 ranks 6,938 pipes	The largest mechanical-action concert hall organ in the US.[24] The largest pipes are made of wood and are about two feet square and 32 feet tall. The smallest pipes are the size of a slender drinking straw. Several of the larger metal pipes are placed in the organ's case to form a visual display, or façade. They are made from an alloy of highly polished tin. These pipes are arranged in a broadly curving arc, and lean outward at a four-degree angle, thereby coinciding with the architecture of the Hall's balconies. This is the first instrument ever constructed with pipes of this size mounted in this manner.[25]
Kotzschmar Memorial Organ	United States	Portland, Maine	Austin Organ Company, 1912	5 manuals 96 ranks 6,554 pipes[26]	This was the second-largest organ in the world when it was built, and is one of only two surviving "municipal organs" in the US.—the other being the Spreckels Organ in San Diego, California.

[While the Visser-Rowland may be the second largest tracker in a concert hall, it is not the second largest in America. That distinction belongs to the 126 rank, 6616 pipe, tracker-action Casavant Opus 3145 (1972) in the Cathedral of Sts. Peter and Paul; Providence, Rhode Island.] http://www.providencecathedral.org/#!cathedral-organ/cyx0

Church organs

Largest church organ per country

Germany	Passau Cathedral Organ, Passau, Germany		5 manuals 242 stops 348 ranks 19,371 pipes	The world's third largest church organ, is the largest organ in Europe. It is also the largest cathedral organ in the world. All the pipes of the organ can currently be played with the gallery console.[31][citation needed]
Italy	Duomo di Milano (Milan Cathedral)	Various	15,350 pipes 254 ranks 185 stops	The organs in this cathedrals history begins in 1395 (the builder was Martino de' Stremidi), and the organs were repeatedly remodelled during subsequent centuries by major Italian builders including Valvassori, Antegnati, Serassi, Tamburini, and Mascioni, as well as some non-Italians such as Bernard d'Allemagna. The golden decoration dates from the 16th century. In 1984 the pipes were reorganised into four cases (north and south), with two console. Actually is the biggest organ in italy and the second in Europe.[citation needed]
Norway	Nidaros Cathedral	G.F. Steinmeyer & Company, Op. 1500, 1929-30 Kuhn Orgelbau, 2013-14	4 manuals 153 stops 201 ranks ~13,000 pipes	Originally commissioned for the 900th anniversary of the Battle of Stiklestad. The organ was soon deemed too big for the cathedral, and as such moved and reduced in size several times through its history. It was in a sorry state for years before a full restoration brought it back to its former glory in 2014.[32] The casing and facade was completely rebuilt to seamlessly fit the western portion of the cathedral, and the organ got a brand new console incorporating modern digital technology. However, the new console has been modeled after the original 1930 console layout, and as many as possible of the old pipes were preserved. New pipes were only made where the original pipes had been lost.[33] In 2015 the new Choir Organ was assimilated into the Steinmeyer Organ, increasing it to 159 stops.

Other notable church organs

• The world's second largest church organ is at the First Congregational Church of Los Angeles, California. Like Passau Cathedral (five organs, one console), it consists of multiple organs playing from twin consoles. Now known as "The Great Organs at First Church," the instruments were installed over a period of approximately 70 years. As of 2023, The Great Organs at First Church consist of 18,094 speaking pipes, 328 ranks, 15 divisions, and a total of 278 speaking stops:
  • The Seeley Wintersmith Mudd Memorial Organ (Chancel) - The church's original instrument, a Skinner Organ built in 1931, is immediately visible upon entering the Sanctuary, flanking either side of the Chancel.
  • Frank C. Noon Memorial Organ (West Gallery) - In 1969, a Schlicker Organ was installed by Organist in residence, Lloyd Holzgraf. The organ's look and sound "enables the organist to capture the spirit and inspiration of the North German tradition of the 17th century."^[40]
  • The Italian Division (Chancel) - A small Italian-style Continuo Organ built by Schlicker, situated adjacent to the South Choir of the Chancel.
  • The Holzgraf Trumpet Royale (Chancel) - These powerful trumpets were installed in 1984, in honor of Mr. Holzgraf's 25th Anniversary at First Church.
  • The Gospel and Epistle Divisions (North and South Transepts) - Under the direction of the famed Frederick Swann, Organist in Residence from 1998 to 2001, William Zeiler completed the installation of Divisions in the North Transept Gallery (Gospel) and the South Transept Gallery (Epistle), so that those attending services and concerts at First Church are now surrounded by music on four sides.

The Moller Consoles were installed during renovations in the early 1990s, replacing the original duplicate Schlicker consoles of 1969 which had become outdated and could no longer fully control the many new additions. The Chancel console, installed in 1992, is known to be one of the last works from the Moller firm, which closed its doors that same year.^[41] Its twin, the Gallery console, was completed by former Moller craftsmen at the Hagertown Organ Company. The Moller Consoles are the largest draw-knob consoles ever built in the Western Hemisphere.

The current organist in residence, Christoph Bull, hosts a free playlist of videos featuring The Great Organs at First Church, for those interested in hearing the instrument in action.

• The Salt Lake Tabernacle organ in Utah is among the largest church organs in the United States and is considered to be one of the finest examples of the American Classic style of organ building.^[42][43] Inspired by the design of the Boston Music Hall organ (now in Methuen, Mass.), the original organ was built in 1867 by Joseph Ridges. At that time, the instrument contained some 700 pipes and was constructed of locally derived materials as much as possible. The distinctive casework has become iconic from its association with the famous choir, and is easily recognized around the world. The pipes are constructed of wood, zinc, and various alloys of tin and lead. When it was initially constructed, the organ had a tracker action and was powered by hand-pumped bellows; later it was powered by water from City Creek. Today it is powered by electricity and has an electro-pneumatic action. Though the organ has been rebuilt and enlarged several times since 1867, the original iconic casework and some of Ridges' pipes still remain in the organ today.^[44] The current organ is largely the work of G. Donald Harrison of the former Aeolian-Skinner organ firm. It was completed in 1948 and contains 11,623 pipes, 147 speaking stops and 206 ranks.^[44]
• Aside from the multiple 100" and 50" stops^[9] on the Atlantic City Boardwalk Hall Auditorium organ, one of the most powerful organ stops in the world are the State Trumpet on the Great Organ at the Cathedral of St. John the Divine in New York City,^[45] and the Trompette Millitaire and Tuba Magna on the organ of Liverpool Anglican Cathedral, UK. Ophicleide (organ stop)^{[citation needed]} These distinctive-sounding stops operate on 50" of wind pressure and are each as loud as an entire large organ played on their own.^{[citation needed]}
• The 1980-pipe Ferris Tracker organ in Round Lake, New York was originally built in 1847 for Calvary Episcopal Church in New York City. It was moved to the Round Lake Auditorium in 1888, and is considered to be the oldest and largest three-manual still intact in the United States.^[46][47]
• The largest fully mechanical pipe organ in Europe is located in the St. Laurenschurch in Rotterdam, The Netherlands. It has 4 Manuals, 5 Divisions, 85 Stops, 7600 Pipes and is 23 meters tall. The organ was completed in 1973, built by Marcussen & Søn from Denmark.
• The largest mechanical action organ in North America is a 4 Manual, 5 Division, 74 stop instrument, with 6,616 pipes & 126 Ranks. The organ was built by Casavant Frères of St Hyacinthe, Quebec for the Cathedral of Sts. Peter and Paul in Providence, Rhode Island in 1972. http://musiqueorguequebec.ca/orgues/etatsunis/providencespsp.html

Organs with notable construction methods

• The Bamboo Organ at St. Joseph's Roman Catholic Church in Las Piñas, Philippines, some 12 km from downtown Manila, is made almost entirely of bamboo. The building of the organ was begun in 1816 by the Spanish Augustinian Recollect, Fr. Diego Cera de la Virgen del Carmen, and completed in 1824. It has been damaged repeatedly over the years but always restored. After its restoration in 1975 by Johannes Klais (Bonn, Germany), a yearly International Bamboo Organ Festival has been held every year (second half of February). Recordings of the organ (by titular organist Armando Salarza, Guy Bovet, Hans and Martin Haselböck, L.Ferdinando Tagliavini exist and) are available online from www.bambooorgan.org
• The main exhibit in the Ontario Science Centre in Toronto, Ontario is a hydraulophone, a kind of water-jet organ. This pipe organ has hydraulic action provided by three water pumps and the keys on the organ console are water jets, so that each "key" (water jet) affords a richly intricate means way to independently control volume, pitch, and timbre affecting each of the organ pipes. See Opening and Lesson (how to play it).
• The 5/80 Wurlitzer Theatre Organ in the residence of Jasper and Marian Sanfilippo of Barrington, Illinois, USA is considered to be the finest example of extension organ in the world today. It is the 3rd largest theatre pipe organ in the world. The 2nd largest theatre pipe organ in the world is in Mesa Arizona at the Organ Stop and the largest theatre pipe organ in the world is the Carma Laboratories organ located in Franklin Wisconsin. ^{[48] [49]} The Sanfilippo organ was designed by David Junchen and installed in a purpose-built music room.
• The Organ of the Basilica of St. Martin (Weingarten), Weingarten, Württemberg, Germany, is built around six church windows, with a detached console facing the church. The tracker action is entirely mechanical, sometimes spanning as much as 20 metres, and going around several corners. It was built by Joseph Gabler during 1713 - 1750. Photos and details can be viewed here.

Other organs

• Old Salem in Winston-Salem North Carolina has a Tannenberg Organ that was originally built in the 18th century. The case was built in Salem and the other parts were built in Lititz. Tannenberg was 72 at the time of the organ's construction, and was not able to make the trip to Salem to install it. The installation was done by George Currie of Philadelphia. Restoration of the organ has been made several times. One undertaking, in 1910, was not satisfactory, and in 2004 an extensive restoration was completed in Staunton, Va. It was then moved into the Visitor Center, where it is played by the Music Director of the museum. A tour of the bellows is available to visitors.
