The Fort of São Teodósio, also known as Fort of São João or Fort of Cadaveira, is located on Praia da Poça with Avenida Marginal on the north side, in São João do Estoril, in the parish of Cascais and Estoril, in the Municipality of Cascais, in the Lisbon Metropolitan Area.

It included a series of maritime fortifications carried out during the period of the Restoration of Independence, in order to protect the entire coast from the Belém Tower, in Lisbon, to Cabo da Roca, in Sintra, avoiding possible enemy landings. Together with the fort of São Pedro, its construction began in April 1642, and was completed the following year. Its location allowed the use of crossfire in conjunction with Fort Santo António, in order to protect Praia da Poça. It was named in honor of Prince D. Teodósio, Duke of Bragança, eldest son of João IV of Portugal, and was also known as Forte d’Assubida, as it is located at the top of the Cadaveira ramp.

It was classified as a Property of Public Interest through Decree nº 129 of September 29, 1977.

Description

Erected then on the bank of the mouth of the Ribeira da Cadaveira, overlooking the beach of Poça, its construction was commanded by António Luís de Meneses, 1st Duke of Marialva. Its layout is similar to that of the other small-sized fortifications erected at the time, with a quadrangular plan, divided into two rectangular spaces that corresponded to the battery, with parapet and facing the sea, and to the accommodation, over which the terrace, parapet for rifle fire, from the landward side. These are concentrated in a vaulted building and were subsequently divided into three dependencies, of which the central one formed the courtyard from which access was made to the barracks and the magazine, arranged on the side.

History

The fort, with 17th century origins, was originally protected by a curtain of trenches, and at the end of the 17th century this defensive line was reinforced with an outer curtain. In the 18th century, three watchtowers were built in three corners of the fort. Later that same century, it is reported that the fort is in ruins, but in 1805 it served as a shelter for troops trying to prevent the disembarkation of ships due to cholera. During the Portuguese Civil War, the fort gained relevance again, having been restored in June 1831.

In 1843, after losing its defensive functions, it was donated to the Santa Casa da Misericórdia de Cascais. Later, in 1942, the construction of the Estrada Marginal required the demolition of some of the parapets of the fort, after which it was handed over to the Fiscal Guard, which remained responsible for the property until the 21st century.

The building, currently in poor condition, was taken over by the Cascais City Council in 2003, with a project for its requalification and use as a tea house and exhibition areas, with completion scheduled for October 2006. In 2023, the fort was in ruins.
