Between 1581 and 1582, there were different descriptions of incursions by pirates and privateers to the island of Santa Maria by Gaspar Frutuoso. Sometime during the 17th century, it was likely that the fort was constructed, at a time when the Captain-major, João Falcão de Sousa, exercised his position as superintendent for the island's defense. A 1717 report described these defenses as: In 1815, there is a reference to the fortification by José Carlos de Figueiredo: On 28 February 1906, the fort was ceded to the municipal authority by the Secretaria de Guerra. The walls of the fort were partially destroyed during the night, and its place a balustrade replaced the curtains. The interior monument was inaugurated on 4 October 1929. During the 1960s, the fort was reconstructed by municipal council. Completed four years later, the fort was re-inaugurated on 11 December 1966. It was at about this time that the movement to take control of the fort began in 1969; the council was interested in obtaining the right to the building of the old barracks, which was under the control of the Ministério das Finanças, in order to demolish the structure for imperativos de urbanização. The ruined structure was constituted by a two-story building, with an area of, a small terrace house that was and a vaulted magazine in ruins, with. The fort was finally ceded to the municipal council in 1970, obliging it to maintain the buildings and the other constructions that existed onsite. on the 30 March 1970, the city solicited the DGEMN to repair the building, since the municipal council did not have the conditions to complete the task. In order to revitalize the space, in 1978, the barracks building was adapted to act as a teahouse, by the Direção dos Serviços dos Monumentos Nacionais. The project envisioned the maintenance of the structure, and resulted in the renovation of the interior, including the fenestrations in order to adapt to the new uses. But, the municipal council eventually ceded the site to the Clube Motard de Santa Maria, following a lease agreement that established a term of 10 years.
Architecture
The fort is situated at the extreme southern edge of the urban escarpment, perpendicular to the coast, from which extends the town, from a dominant position above the valley of São Francisco, creating a lookout. It is located on an escarpment that descends slightly from the northeast, forming a small square on various terraces lined with Portuguese pavement. The western edge is delimited by a small wall with bunks covered in pergola. At the centre of the fort is a monument in granite that pays homage to the crew of the minesweeper Augusto de Castilho. Below the main structure, and complementing this structure, were two, smaller redoubts, known as the Fortins das Areias. Surrounding the main walls are other buildings of architectural importance. The maritime fort was constructed in the 17th century, and altered according to historical changes, forming a bastion adopted to the morphology and orientation of its base. It is an irregular trapezoid oriented to the views of the sea, but only conserves a cylindrical bartizan from its period of defense. The structure is decorated with a cordon of merlon parapets and canon emplacements, except on the side oriented to land, where an arched portico is decorated with cornice. To the right of the fort's portico is a stone inscription in relief: FORTE DE / S. BRÁS. The walls oriented to the sea is the most conserved. Addorsed to the northern wall is the Hermitage of Nossa Senhora da Conceição, which is taller than the main structure, while to the right of the entrance is the building for the former-command and barracks. This two-story building is integrated into the structure with a second-story balcony accessible from staircase. The interior of the fort is lower than the exterior, paved and presenting a portico with various steps to complement the distance. The building used for the command and barracks is square, covered in double tile, with simple edge. The facades are singular or double-story, with the principal facade oriented towards the south. The two-story building, is plastered and painted in white with granite cornerstones, and a staircase that provides access to the second floor by way of balcony. The second floor includes framed door and window, with the doorway off of centre. On the main floor are two rectangular, framed doors under the balcony that are aligned with the same window-door combination on the second story. The left lateral facade, oriented towards the port is marked by a window, just over the parapet, while the lateral right is barren. To the rear is a guillotine-style window. The canon emplacements of the fort have nine artillery pieces, over wood bases. The bartizan can be accessed by square opening.
