The 'Rosa dos Ventos' (Wind Compass) found on site measures 43 meters in diameter and was rediscovered under a layer of earth in the 20th century.
The site was historically known as the 'Sacrum Promontorium' by ancient Roman geographers, who believed it was the place where the gods rested at night.
The fortress was significantly damaged by the 1755 Lisbon earthquake and subsequent tsunami, requiring extensive reconstruction.
Sir Francis Drake attacked the fortress in 1587 during his raid on the Spanish fleet, causing major damage to the existing structures.
The interior contains no permanent navigational school, debunking the persistent myth that a formal academy existed here under Prince Henry.
Sagres Fortress is a 15th-century defensive structure located on the Ponta de Sagres, a promontory projecting into the Atlantic Ocean. The site is historically associated with the Age of Discovery and Prince Henry the Navigator. The perimeter wall features a massive 16th-century gate that leads to an expansive, windswept plateau. Inside the walls, the 16th-century Church of Nossa Senhora da Graça remains standing. A large stone wind compass, the Rosa dos Ventos, is embedded into the ground within the fortress grounds. The site is defined by its dramatic cliffs, which reach heights of 40 meters above the sea. Archaeological excavations have identified the remains of various historical buildings and remnants of older fortification layers. The fortress serves as a national monument and a significant landmark for maritime history in Portugal. It is currently open to the public and remains a key site for cultural tourism in the Algarve region.

Bring a windproof jacket regardless of the season, as the promontory is subject to constant, high-velocity coastal winds.
Wear sturdy, closed-toe walking shoes to navigate the uneven terrain and rocky paths around the cliff edges.
Walk the full perimeter path for unobstructed views of the Atlantic and the neighboring Cape Saint Vincent lighthouse.
Plan for high sun exposure as there is almost no natural shade across the expansive, exposed plateau.
Do not attempt to climb down the cliff faces or stray from marked paths, as the ground is prone to erosion and rockfall.
Open daily throughout the year, but may close during extreme weather conditions such as high-velocity storms.
Stay strictly within the designated paths and behind safety barriers; cliff edges are unstable and dangerous.
