 On 23 June 1727 a truce was agreed, and a peace treaty was signed in 1729 after long negotiations.At the start of the Great Siege of Gibraltar (June 1779 – 7 February 1783), engineers built a "cavalier" (elevated firing platform) for five guns within the north bastion, by then considered a part of the Grand Battery.Before 1999, the site of the Giralda Tower was partly an unkept garden, and is now used by the Gibraltar Petanque Association.
