The walled city had two main gates, St. Mary's and St. Nicholas'. The former, which stood close to St. Philip's Bastion, led into the town along the main street (Calle Mayor). The second was located between the Queen's Bastion and the Leiva Bastion. A ravelin was erected in front of St. Nicholas' Gate and another (the Guevara or Mary Magdalene Ravelin) between the Leiva Bastion and the Mary Magdalene Turret. These were practically demolished during the French siege of 1719.
