Beliche cove marks the meeting point between southern and western Portugal, a setting where the sea and cliffs seem to clash. High above stands the Fort of Santo António de Belixe, a guardian of centuries and storms. Built before the 16th century, it survived attacks, reconstructions, and the 1755 earthquake, later being reborn as an inn. Nearby, the chapel of Santa Catarina, commissioned by Prince Henry the Navigator, serenely watches over the abyss. The views? Breathtaking: the Atlantic and the cliffs merge in a spectacle of pure grandeur.

The Fort of Santo Alberto do Pessegueiro, also known as the Fort of Pessegueiro Island or the Fort of Ilha de Fora, is located on the Alentejo coast, on the island of Pessegueiro, in the parish of Porto Covo, municipality of Sines, district of Setúbal, in Portugal. It crossed fires, on the mainland, with another maritime fort: the Fort of Nossa Senhora da Queimada do Pessegueiro, also known as the Fort of Praia do Pessegueiro or the Fort of Ilha de Dentro, in a dominant position over Pessegueiro beach. Both were part of a larger project to defend the Costa Vicentina, which included an artificial port sheltered by a stone breakwater that would connect the island of Pessegueiro to the bordering islet of Penedo do Cavalo and this islet to the mainland. They are currently located in the area of the Southwest Alentejo and Costa Vicentina Natural Park.
