The cave is high on the east cliff of the rock and has not been studied in detail although it has great archaeological potential. The cave used to house a large colony of Myotis and Miniopterus bats which seem to have now abandoned the cave.

Holy Boys Cave is named after the Royal Norfolk Regiment and the Royal East Anglian Regiment, known as the Holy Boys. They were stationed in Gibraltar in the late 1800s. The reason why it is called Holy Boys Cave is due to graffiti found within the cave which reads IX Regiment of Foot. The 9^th Regiment of Foot or Royal Norfolk Regiment had earned the nickname The Holy Boys during the Peninsular War in Spain on account of their regimental badge which had Britannia on it. The Spanish populace thought this was the Virgin Mary and hence the name. They were stationed in Gibraltar in the late 19th Century.
