Built by the Moors, Lagos' castle was conquered by Christian forces in the 13th century. It's said that the ill-fated, evangelical Dom Sebastião attended an open-air Mass here and spoke to the assembled nobility from a small Manueline window in the castle before leading them to a crushing defeat at Alcácer-Quibir (Morocco). Admire the window for as long as you can bear the urine smells from the previous night's party, then check out the nearby bastion and gateway.
