A blue plaque is a permanent sign installed in a public place in the United Kingdom and elsewhere to commemorate a link between that location and a famous person, event, or former building on the site, serving as a historical marker. The term is used in the United Kingdom in two different senses. It may be used narrowly and specifically to refer to the "official" scheme administered by English Heritage, and currently restricted to sites within Greater London; or it may be used less formally to encompass a number of similar schemes administered by organisations throughout the UK.
The "official" scheme traces its origins to that launched in 1866 in London, on the initiative of the politician William Ewart, to mark the homes and workplaces of famous people. It has been administered successively by the Society of Arts (1866–1901), the London County Council (1901–1965), the Greater London Council (1965–1986) and English Heritage (1986 to date). It remains focused on London (now defined as Greater London), although between 1998 and 2005, under a trial programme since discontinued, 34 plaques were erected elsewhere in England. The first such scheme in the world, it has directly or indirectly provided the inspiration and model for many others.
Many other plaque schemes have since been initiated in the United Kingdom. Some are restricted to a specific geographical area, others to a particular theme of historical commemoration. They are administered by a range of bodies including local authorities, civic societies, residents' associations and other organisations such as the Transport Trust, the Royal Society of Chemistry, the Music Hall Guild of Great Britain and America, the Centre for Pagan Studies and the British Comic Society. The plaques erected are made in a variety of designs, shapes, materials and colours: some are blue, others are not. However, the term "blue plaque" is often used informally to encompass all such schemes.
There are also commemorative plaque schemes throughout the world such as those in Paris, Rome, Oslo, Dublin; and in other cities in Australia, Canada, the Philippines, Russia and the United States. These take various forms, and they are more likely to be known as commemorative plaques or historical markers.
The original blue plaque scheme was established by the Society of Arts in 1867, and since 1986 has been run by English Heritage. It is the oldest such scheme in the world. Since 1984 English Heritage have commissioned Frank Ashworth to make the plaques which have then been inscribed by his wife, Sue, at their home in Cornwall.
English Heritage plans to erect an average of twelve new blue plaques each year in London.
After being conceived by politician William Ewart in 1863, the scheme was initiated in 1866 by Ewart, Henry Cole and the Society of Arts (now the Royal Society of Arts), which erected plaques in a variety of shapes and colours.
The first plaque was unveiled in 1867 to commemorate Lord Byron at his birthplace, 24 Holles Street, Cavendish Square. This house was demolished in 1889. The earliest blue plaque to survive, also put up in 1867, commemorates Napoleon III in King Street, St James's. Byron's plaque was blue, but the colour was changed by the manufacturer Minton, Hollins & Co to chocolate brown to save money.
In total the Society of Arts put up 35 plaques, fewer than half of which survive today. The Society only erected one plaque within the square-mile of the City of London, that to Samuel Johnson on his house in Gough Square, in 1876. In 1879, it was agreed that the City of London Corporation would be responsible for erecting plaques within the City to recognise its jurisdictional independence. This demarcation has remained ever since.
In 1901, the Society of Arts scheme was taken over by the London County Council (LCC), which gave much thought to the future design of the plaques. It was eventually decided to keep the basic shape and design of the Society's plaques, but to make them uniformly blue, with a laurel wreath and the LCC's title. Though this design was used consistently from 1903 to 1938, some experimentation occurred in the 1920s, and plaques were made in bronze, stone and lead. Shape and colour also varied.
In 1921, the most common (blue) plaque design was revised, as it was discovered that glazed Royal Doulton stoneware was cheaper than the encaustic formerly used. In 1938, a new plaque design was prepared by an unnamed student at the LCC's Central School of Arts and Crafts and was approved by the committee. It omitted the decorative elements of earlier plaque designs, and allowed for lettering to be better spaced and enlarged. A white border was added to the design shortly after, and this has remained the standard ever since. No plaques were erected between 1915 and 1919, or between 1940 and 1947, owing to the two world wars. The LCC formalised the selection criteria for the scheme in 1954.
When the LCC was abolished in 1965, the scheme was taken over by the Greater London Council (GLC). The principles of the scheme changed little, but now applied to the entire, much larger, administrative county of Greater London. The GLC was also keen to broaden the range of people commemorated. The GLC erected 252 plaques, the subjects including Sylvia Pankhurst, Samuel Coleridge-Taylor, and Mary Seacole.
In 1986, the GLC was disbanded and the blue plaques scheme passed to English Heritage. English Heritage erected more than 300 plaques in London.
In January 2013 English Heritage suspended proposals for plaques owing to funding cuts. The National Trust's chairman stated that his organisation might step in to save the scheme. In the event the scheme was relaunched by English Heritage in June 2014 with private funding (including support from a new donors' club, the Blue Plaques Club, and from property developer David Pearl). Two members of the advisory panel, Professor David Edgerton and author and critic Gillian Darley, resigned over this transmutation, concerned that the scheme had been "reduced to a marketing tool for English Heritage".
In April 2015, English Heritage was divided into two parts, Historic England (a statutory body), and the new English Heritage Trust (a charity, which took over the English Heritage operating name and logo). Responsibility for the blue plaque scheme passed to the English Heritage Trust.
To be eligible for an English Heritage blue plaque in London, the famous person concerned must:
In cases of foreigners and overseas visitors, candidates should be of international reputation or significant standing in their own country.
With regards to the location of a plaque:
Other schemes have different criteria, which are often less restrictive: in particular, it is common under other schemes for plaques to be erected to mark the sites of demolished buildings.
Almost all the proposals for English Heritage blue plaques are made by members of the public who write or email the organisation before submitting a formal proposal.
English Heritage's in-house historian researches the proposal, and the Blue Plaques Panel advises on which suggestions should be successful. This is composed of 9 people from various disciplines from across the country. The panel is chaired by Professor Ronald Hutton. The actor and broadcaster Stephen Fry was formerly a member of the panel, and wrote the foreword to the book Lived in London: Blue Plaques and the Stories Behind Them (2009).
Roughly a third of proposals are approved in principle, and are placed on a shortlist. Because the scheme is so popular, and because a lot of detailed research has to be carried out, it takes about three years for each case to reach the top of the shortlist. Proposals not taken forward can only be re-proposed once 10 years have elapsed.
A small minority of GLC and English Heritage plaques have been erected to commemorate events which took place at particular locations rather than the famous people who lived there.
In 1998, English Heritage initiated a trial national plaques scheme, and over the following years erected 34 plaques in Birmingham, Merseyside, Southampton and Portsmouth. The scheme was discontinued in 2005. Although English Heritage no longer erects plaques outside Greater London, it does provide advice and guidance to individuals and organisations interested or involved in doing so.
The popularity of English Heritage's London blue plaques scheme has meant that a number of comparable schemes have been established elsewhere in the United Kingdom. Many of these schemes also use blue plaques, often manufactured in metal or plastic rather than the ceramic used in London, but some feature plaques of different colours and shapes. In 2012, English Heritage published a register of plaque schemes run by other organisations across England.
The criteria for selection varies greatly. Many schemes treat plaques primarily as memorials and place them on the sites of former buildings, in contrast to the strict English Heritage policy of only installing a plaque on the actual building in which a famous person lived or an event took place.
The Corporation of London continues to run its own plaque scheme for the City of London, where English Heritage does not erect plaques. City of London plaques are blue and ceramic, but are rectangular in shape and carry the City of London coat of arms. Because of the rapidity of change in the built environment within the City, a high proportion of Corporation of London plaques mark the sites of former buildings.
Many of the 32 London boroughs also now have their own schemes, running alongside the English Heritage scheme. Westminster City Council runs a green plaque scheme, each plaque being sponsored by a group with a particular interest in its subject. The London Borough of Southwark started its own blue plaque scheme in 2003, under which the borough awards plaques through popular vote following public nomination: living people may be commemorated. The London Borough of Islington has a similar green heritage plaque scheme, initiated in 2010.
Other plaques may be erected by smaller groups, such as residents' associations. In 2007 the Hampstead Garden Suburb Residents Association erected a blue plaque in memory of Prime Minister Harold Wilson at 12 Southway as part of the suburb's centenary celebrations.
In Northern Ireland the Ulster History Circle is one of a small number of groups administering blue plaques. Established in 1983, it has erected around 140 plaques. Belfast City Council also has a scheme.
|Aldershot||In 2017 in Aldershot in Hampshire the Aldershot Civic Society unveiled its first blue plaque to comedian and actor Arthur English at the house where he had been born. It is intended that this will be the first in a series dedicated to notable local people or historic buildings.|
|Berkhamsted||The Hertfordshire town of Berkhamsted unveiled a set of 32 blue plaques in 2000 on some of the town's most significant buildings, including Berkhamsted Castle, the birthplace of writer Graham Greene and buildings associated with the poet William Cowper, John Incent (a Dean of St. Paul's Cathedral) and Clementine Churchill. The plaques feature in a Heritage Trail promoted by the town's council.|
|Birmingham||The Birmingham Civic Society provides a blue plaque scheme in and around Birmingham: there are over 90 plaques commemorating notable former Birmingham residents and historical places of interest.|
|Bournemouth||Bournemouth Borough Council has unveiled more than 30 blue plaques. Its first plaque was unveiled on 31 October 1937 to Lewis Tregonwell, who built the first house in what is now Bournemouth. Two further plaques followed in 1957 and 1975 to writer Robert Louis Stevenson and poet Rupert Brooke respectively. The first blue plaque was unveiled on 30 June 1985 dedicated to Percy Florence Shelley.|
|Derbyshire||In 2010, Derbyshire County Council allowed its residents to vote via the Internet on a shortlist of notable historical figures to be commemorated in a local blue plaque scheme. The first six plaques commemorated industrialist Richard Arkwright junior (Bakewell), Olave Baden-Powell and the "Father of Railways" George Stephenson (Chesterfield), the mathematical prodigy Jedediah Buxton (Elmton), actor Arthur Lowe (Hayfield), and architect Joseph Paxton (Chatsworth House).|
|Gateshead||A long-running blue plaque scheme is in operation in Gateshead. Run by the council, the scheme was registered with English Heritage in 1970 and 29 blue plaques were installed between the inception of the scheme in 1977 and the publication of a commemorative document in 2010. The Gateshead scheme aims to highlight notable persons who lived in the borough, notable buildings within it and important historical events. Some of those commemorated through the scheme include Geordie Ridley, author of the "Blaydon Races": William Wailes, a 19th-century proponent of stained glass; the industrialist and co-founder of Clarke Chapman, William Clarke and Sir Joseph Swan, inventor of the incandescent light bulb. More recent plaques (both erected in 2012) have commemorated Vincent Litchfield Raven, the chief mechanical engineer at the North Eastern Railway; and the 19th-century Felling mining disasters.|
|Leeds||Leeds Civic Trust started its blue plaque scheme in 1987 and by 2020 had 180 plaques.|
|Loughton||The Essex town of Loughton inaugurated a scheme in 1997 following a programme allowing for three new plaques a year; 42 had been erected by 2019. The aim is to stimulate public interest in the town's heritage. Among the Loughton blue plaques is that to Mary Anne Clarke, which is in fact a pair of identical plaques, one on the back, and one on the front, of her house, Loughton Lodge.|
|Malvern||In 2005, Malvern Civic Society and Malvern Hills District council announced that blue plaques would be placed on buildings in Malvern that were associated with famous people, including Franklin D. Roosevelt. Since then blue plaques have been erected to commemorate C. S. Lewis, Florence Nightingale, Charles Darwin and Haile Selassie.|
|Manchester||A scheme in Manchester is co-ordinated by Manchester Art Gallery, to whom nominations can be submitted. Plaques must be funded by those who propose them. From 1960 to 1984 all plaques were ceramic, and blue in colour. From 1985, they were made of cast aluminium, colour-coded to reflect the type of commemoration (blue for people; red for events in the city's social history; black for buildings of architectural or historic interest; green for other subjects). After a period of abeyance, the scheme has been revived and all plaques are now patinated bronze.|
|Oldham||A blue plaque at Oldham's Tommyfield Market (Greater Manchester) marks the 1860s origin of the fish and chip shop and fast food industries.|
|Oxfordshire||The Oxfordshire Blue Plaques Board places plaques in the city of Oxford and elsewhere in the county.|
|Swindon||Swindon Heritage installs blue plaques in Swindon to commemorate the famous people, places and events which are part of the town's history. These are financed through public donations from individuals and groups. The first plaque to be unveiled was to the suffragette Edith New in March 2016. Others commemorated include the writer and naturalist Richard Jefferies the actress Diana Dors.|
|Wolverhampton||Wolverhampton has over 90 blue plaques erected by the Wolverhampton Civic and Historical Society in a scheme which started in 1983. One of the more unusual plaques marks the location of the World Altitude Balloon Record on Friday 5 September 1862.
In 2021, a Black Lives Matter plaque was erected at the Wolverhampton Heritage Centre (the former constituency office of Enoch Powell, where his Rivers of Blood speech was written) to commemorate immigrant rights activist Paulette Wilson, a member of the Windrush generation.
|York||York Civic Trust has operated a blue plaque scheme since the 1940s. Plaques erected by the Trust use a variety of shapes and materials, including bronze, wood, slate, aluminium, and glass, and commemorate buildings and events as well as people. All plaques bear the emblem of the Civic Trust, which is based on the York assay mark of 1423. An aesthetically notable plaque placed through the scheme is that to Anne Lister, 'lesbian and diarist', which is surrounded by rainbow.|
There also exist several nationwide schemes sponsored by special-interest bodies, which erect plaques at sites or buildings with historical associations within their particular sphere of activity.
