Fort of Santo António de Belixe, Military fortress at Cape St. Vincent, Sagres, Portugal
The Fort of Santo António de Belixe is a military stronghold perched on rocky cliffs above Beliche Bay at the southwestern tip of Portugal. It features a distinctive star-shaped design with defensive batteries positioned to command views across the Atlantic Ocean and surrounding coastal waters.
The fort was built in the 16th century to defend the southwestern coast against raids, but suffered severe damage during an attack by English captain Francis Drake in 1578. Reconstruction efforts extended for decades and were finally completed under King Philip III's reign.
The chapel inside the fort was originally dedicated to Saint Catherine and later renamed in honor of Saint Anthony, reflecting the spiritual life that once existed within these walls. Visitors today can still see the royal coat of arms of King Sebastian displayed throughout the structure.
The site sits on an exposed, windy cape best approached on foot from a nearby parking area, with access to the fort itself depending on pathway conditions. Visitors should prepare for changeable weather and uneven terrain, and should explore the surrounding area carefully when walking around the structures.
The fort is an active research site where scientists monitor the structure to understand how coastal erosion threatens it over time. These ongoing investigations directly shape how the site is preserved and help ensure the fortress remains intact for future visitors.
