Castelo de Sines

Castelo de Sines is a medieval fortress perched on a cliff overlooking the Atlantic Ocean, fortified with thick walls, towers, and a fortified courtyard at its center. Today it houses a museum and exhibitions dedicated to Vasco da Gama, offering visitors a view into maritime history and local heritage through its collections.

The fortress was built in the first half of the 15th century after the crown granted administrative independence to Sines and ordered defensive structures to be constructed. It marks a pivotal moment in Portugal's rise as a maritime power during the age of oceanic voyages.

The fortress is closely tied to navigator Vasco da Gama, who was born within its walls. His father commanded the castle, making it a landmark connected to the age of Portuguese maritime exploration.

The site sits on elevated ground right by the ocean, giving visitors views of the coastline while exploring the fortification. The outdoor areas allow you to walk and understand how the structure commands the landscape.

The outer courtyard called Terreiro functions as an open-air venue where the town hosts cultural events and gatherings throughout the year. This gives the fortress an active role in the community beyond its historical importance.
