The history of São Marcelo Fort dates back to the early 17th century. Built on a sandbank in Todos os Santos Bay, opposite the lower town of Salvador, it is notable for its almost circular layout and its role in defending the harbour entrance.
Origin and construction
Construction began in the 17th century to protect Salvador from attacks from the sea. Initially a temporary structure, the fort was reinforced with stone and lime, with an artificial rockfill to stabilise the foundations and allow a 360° field of fire across the bay.
Periods of conflict
In 1624, the fort was occupied by the Dutch during the invasion of Salvador; in subsequent incidents, it helped to repel further attempts at invasion. Over the years, it was also used as a prison for rebels and political prisoners.
Architectural alterations
The structure underwent modifications — turrets, parapets, casemates and internal alterations — in line with defensive requirements and technological developments. Rock-filling and foundation works were carried out periodically due to its location on the open sea.
Decline, restoration and current use
As it became obsolete for military purposes, the fort was decommissioned. It underwent restoration work in the 20th and early 21st centuries and now serves as a tourist and cultural attraction, welcoming visitors on guided tours and for events when it is open to the public.
