Sagres sits at the southwestern edge of continental Europe in Portugal’s Algarve region, where the Atlantic’s wide horizon meets rugged cliffs and open skies. For centuries this point was linked to maritime adventure and visitors can still feel that sense of discovery in the air.

The higher part of the city, the old quarter, inside the still extant fortifications with its timber houses, should be visited.
