San Francisco Fort, affectionately known as "the cheese fort" due to its modest size, overlooks São Francisco Beach in the Farol neighborhood of Olinda. Constructed in the late 1620s as a brushwood and earth redoubt under Matias de Albuquerque during threats of Dutch invasion, it exemplifies the defensive fortifications built along Pernambuco's coast. The original structure was significantly rebuilt during the 19th century and underwent comprehensive restoration in the 1970s. Located at Largo do Fortim, the fort features cannons mounted on granite bases facing the Atlantic, surrounded by colorful colonial architecture and vibrant coastal atmosphere. The site encapsulates Olinda's maritime heritage while remaining an active landmark within the town's historic district.
