Castelo de Aljezur

The castle is the reason Aljezur looks the way it does: a ruined fortress on a schist hill directly above the old town, with the river valley spread out below. The municipality describes the view east over the Aljezur plain toward the Serra de Monchique, and west down the valley the river follows to the sea at Praia da Amoreira [1].

The history, briefly. The castle was built in the 10th century and was the last Islamic castle in the Algarve to be taken by Christian forces, in 1249 [1]. It lost its purpose and fell into ruin around the turn of the 16th century, as the river silted up and stopped being navigable [1][3]. Two towers — one round, one square — and a vaulted cistern survive; excavations found traces of occupation from the Bronze Age onward [1]. It is a listed monument (Imóvel de Interesse Público) [1].

Who it suits. A good short outing on a grey or windy day when the beaches are not an option — for families as a “real castle” stop, for nomads as a sunset walk up from the old town. The site is a rocky hilltop ruin, so expect uneven ground.

Getting there. On foot up through the old town, or by car to a small parking area at the top, according to visitor reviews [2]. Reviewers also describe entry as free [2]; we found no official confirmation.
