  2. 11th centurySilves became the capital of an autonomous taifa kingdom, and the castle's defenses reached their height.
  3. 12th–13th centuriesAlmoravid and Almohad campaigns shaped the walls and towers. The inner fortress was probably built under Almohad rule.
  4. 1189King Sancho I and a Crusader army captured Silves after a long siege.
