Silves, was once the Moorish capital of the Algarve. Its imposing red sandstone castle was the scene of horrific medieval battles between Islamic Moors and Christians. Some of the crusaders who fell in the battle are entombed in the cathedral next to the castle. Both the castle and cathedral are open to visitors.

Today Silves is a quiet market town in the midst of the AlgarveĀ“s main citrus-growing area. Cork is processed locally. The town hosts two annual festivals, one celebrating oranges, the other beer. On the third Monday of each month there is a particularly lively open-air market.
