History.
First occupied during the Great Siege of Gibraltar (1779-1783). The battery dates from 1788 although it has a plaque labelled "1903" It is named as the nearby "Hayne's Cave". This battery was named after Captain Haynes who was the garrison quartermaster in 1787-1788 and who began the construction of Queen's Road. Visitors can see the remains of one of the two 4-inch QF gun positions which were installed in 1904 and are about 40 metres apart. In 1911 the guns were removed in favour of the superior 6 inch guns of Tovey Battery.
The cave itself was eventually taken over for water tanks and pumps.
