Forte de Cacela - Largo Ibn Darraj Al-Qastalli
Highlight • Castle
Initially it was under Islamic rule, later, in 1240 it passed to Christian rule.
It has changed over the centuries. In 1755 the earthquake almost completely destroyed it. In 1770 began its reconstruction. Nowadays it continues with the same function, the Fortress is occupied by the Fiscal Guard (GNR) and, for this reason, its interior cannot be visited. The exterior is free and worth the visit, especially the panoramic view over the mouth of the Ria Formosa, which is a beautiful view from this place.

It's definitely worth stopping here, and even taking a break. Unfortunately, the church is often closed, and the "fortress" next to it is also inaccessible.

Initially it was under Islamic rule, later, in 1240 it passed to Christian rule. It has changed over the centuries. In 1755 the earthquake almost completely destroyed it.
