About Castelo do Queijo
Castelo do Queijo is the popular name for Forte de São Francisco Xavier, a 17th-century coastal fort built on a rocky outcrop right at the edge of the Atlantic, in the Foz do Douro area of Porto. It's one of the city's most recognizable coastal landmarks, visible from afar along the seafront promenade.
The fort sits right next to the Felgueiras lighthouse and Praia do Molhe, which makes this stretch of coastline one of the most photographed spots in western Porto. Inside there's a small museum dedicated to the fort's military history, with items and information about its role in coastal defense over the centuries.
How to get there from the park
From Porto City Park, Castelo do Queijo is about 15 to 20 minutes on foot, following the seafront promenade along the coast. It's a simple, well-signposted route, with no need to cross main roads, whether on foot or by bike.
