Ostia (/ˈɒstiə/, Italian: [ˈɔstja]; officially Lido di Ostia) is a large neighbourhood in the Municipio X of the comune of Rome, Italy, near the ancient port of Rome, which is now a major archaeological site known as Ostia Antica. Ostia is also the only municipio or district of Rome on the Tyrrhenian Sea, and many Romans spend the summer holidays there. Therefore it's entirely situated within the Municipality of Rome and is the city's seaside resort.


Main article: Ostia Antica

Ancient Main Road, Ostia Antica

Ostia Antica had been the port city of ancient Rome, and is often referenced in writings from the times of the Roman Republic and the Roman Empire. For Christian posterity, Ostia Antica was especially important as the site of the death of Saint Monica (mother of Saint Augustine) in 387 in a house property of the Diocesi of Rome, on their way back to Africa after Augustine's conversion to Christianity.[1]

An important stand in Italian nationalism of the 19th century was a veneration for the glories of the Roman past, manifested in a wish to revive or recreate various places and institutions connected with Ancient Rome. In 1871, the city of Rome became the capital of the new Kingdom of Italy. A recreation of Ostia was an obvious additional step.

The modern neighbourhood of Ostia was founded in 1884, near the remains of Ostia Antica. This was possible after reclamation of the nearby marshland, which was infested by malarial mosquitos. The first inhabitants were peasants coming from Ravenna, in Romagna. Due to the opening of the urban Roma–Ostia railway in 1924, the new village soon became the favourite sea resort of the Romans, while many Art Nouveau houses were built on the waterfront.

The new village was connected to central Rome through the new Via Ostiense, which was opened in 1907. During the Fascist period, the government massively expanded the neighbourhood, which got its ultimate architectural character due to many new buildings in Stile Littorio. New infrastructure, such as a second road to Rome (Via del Mare'), the promenade, and a water airport, were all built during this period.

After World War II, many bathing establishments were built on the seaside, and Ostia experienced a tourist boom. The new Via Cristoforo Colombo connected Ostia with the EUR district and the center of Rome. The building of the Leonardo da Vinci Airport in Fiumicino in 1956 made Ostia an attractive district for airport and airline workers. Italian intellectual, film director and poet Pier Paolo Pasolini was assassinated near the water aerodrome on 2 November 1975. In 1976, Ostia became part of the X Municipio of the comune of Rome. Nowadays, due to the expansion of the city, only the Park of Castelfusano separates Ostia from the other quarters of Rome.

The Ostia quarter is an active seaside resort, the official seaside resort of the city of Rome, equipped with beaches, dedicated facilities, restaurants, hotels and points of interest. Ostia, due to its historical roots and its natural characteristics, is an important tourist location. It is known and famous, as it was at its origins when it was completely regenerated during the fascist period, as the "Sea of Rome", and consequently has become one of the most populous and sought-after neighborhoods in Rome.[2]

The main (and often crowded) free beaches of Ostia extend in the southern area, protected with dunes and rich in Mediterranean flora.

The neighborhood is located on the Tyrrhenian coast, close to Acilia and separated from Fiumicino by the mouth of the Tiber. Other borders are the pine forest of Castelfusano and Viale dei Promontori, which represents the border with the residential area of Casal Palocco and Infernetto, while to the south it borders with Torvaianica, a frazione of the municipality of Pomezia.

The territory is almost completely flat with small hilly reliefs made up of dunes. The vegetation is composed of Maquis shrubland and there are several centuries-old pine forests made up of domestic and maritime pines, holm oaks, elms and poplars. Ostia has a mediterranean climate. Located on the coast, enjoys warmer winters and cooler summers than central Rome.
