What Castelo de São Filipe looked like in its prime.

Perched on a wooded hill above the Sado estuary, the fortress is an irregular polygon of ochre-brown masonry with six tall, sloping ramparts terminating in angular bastions. A broad, stepped glacis drops to the surrounding pine-clad slopes. The upper platform contains compact whitewashed buildings with red-tile roofs and low eaves; a small baroque chapel sits among them. Curtain walls and ramparts form a stepped, multi-level silhouette against the skyline, with an arched entrance visible on the rampart line.

Its story

The story of Castelo de São Filipe.

Philip II of Spain, Philip I of Portugal, ordered a new fortress above Setúbal in 1582 and personally witnessed the laying of its cornerstone. Named for the king during the Iberian Union, the fort commands the right bank of the mouth of the Sado, overlooking the town centre to its east and guarding access to the river.

The design was by Giovan Giacomo Paleari Fratino, with the Italian military engineer Filipe Terzi, who worked for the Spanish Royal Court, as chief engineer; after Terzi's death it was completed in 1600 under Leonardo Torreano. Recent scholars argue the fort was meant not only to reinforce Setúbal's defences but to protect a garrison loyal to the Philippine Dynasty. The townspeople had shown considerable opposition to Spanish rule.

The irregular polygonal fort carries six tall, sloping ramparts and six bastions, with fortress buildings and a small chapel on its upper platform. It was damaged in the 1755 earthquake, and the Command House, by then the residence of the Governor of Setúbal, was destroyed by fire in the mid-19th century.
