Mértola

The town’s main attraction is its castle, built by the Moors, with a guard tower from the 13th-century. The main church, with its sculpted façade, contains elements from the Manueline period, occupies the site of what once was an ancient mosque. Mértola has three important museum sites as a consequence of the intense archeological activity there. The Roman museum occupies the Town Hall building. The Islamic collection includes the country’s most important archive of ceramic objects (9th to 13th-centuries). Here too is one of the rarest early Christian basilicas in the entire Iberian peninsula (dating from the 5th-century).
