The Ponte da Bandeira Fort is a majestic and well-preserved 17th-century structure at the mouth of the Bensafrim River in central Lagos. It has a robust, rectangular form, having been constructed to fend off pirates and Spanish fleets. Visit the fort’s museum that provides information about Portuguese discoveries.

Enter the impressive structure via the large drawbridge extending across the fort’s moat. Reach the courtyard at the heart of the fort and admire the quaint blue mosaic tiles of the chapel devoted to Santa Barbara, patron saint of miners and artillery soldiers.

The museum contains many exhibits relating to Portuguese discoveries. See the large models of caravels, which are unusual Iberian boats. Learn about the region’s maritime history through the enlightening exhibits. Marvel at the remarkable metal sculptures and see the collection of old weather vanes. The top of the fort has a viewing platform overlooking the water from the marina to the sea. Capture photos of the shimmering Atlantic Ocean.

The stone carving above the main door states that the fort was constructed between 1679 and 1690. Find out via the exhibits and docents about the history and uses of the structure over time. It initially served to protect the mouth of the river and the harbor area from attack. Later, it was a warehouse for military and maritime supplies, before becoming a museum.

The entry fee for the fortress includes access to the museum and chapel. The complex opens Tuesday through Sunday from morning until late afternoon, with a short break at noon.

The Ponte da Bandeira Fort is at the point where the mouth of the Bensafrim River meets the Atlantic Ocean. Walk along the coastal promenade past the historic center to get to this scenic gem. Make sure to see Lagos Marina, the Edge of the Port and the Governor’s Castle in this district.
