Based on the provided search context, there is no mention of a Portuguese church located within or visible from the Fort area. The historical records indicate that the structure originally on the site was a Manor House (Casa da Orta) built by the Portuguese physician and botanist Garcia de Orta in the 1500s.
When the British East India Company took control in 1668, they constructed Bombay Castle around this existing mansion, using it as their administrative base and the residence for the First Governor. While the Portuguese did fortify the area, the context specifically notes that the British destroyed most Portuguese buildings, retaining only specific elements like a gate and a sundial. The prominent church mentioned in the Fort area, St. Thomas Cathedral, was built by the British (construction started in 1672, completed in 1718) and is located near Churchgate,
