Silves is a beautiful medieval town. It was the capital of the Algarve during the period of Arab rule and is known for its rich history and cultural heritage. The town is dominated by its impressive red sandstone castle, which was built by the Moors in the 8th century and later fortified by the Christian kings during the Reconquista. Visitors can explore the castle and its walls, which offer panoramic views of the surrounding countryside. The town's narrow, winding streets are lined with whitewashed houses and traditional shops selling local handicrafts and souvenirs. Other notable landmarks include the 13th-century Cathedral. The market is also a must-see.
