The site of Willis' Hill on which Farringdon's Battery was built came to notice during the Thirteenth Siege of Gibraltar in 1727 when the Spanish besiegers attempted to mine under the British positions on the Rock in an attempt to blow them up.

Farrington only briefly held this position but he had also been in Gibraltar from 1759 to 1763 before he had left to fight in the American War of Independence.

[3] The battery's name seems to have been corrupted to be spelt with a "d" early on as John Drinkwater Bethune spells it this way in his A history of the late siege of Gibraltar in 1786.

It is likely that the 10 inch gun at Parson's Lodge Battery near Rosia Bay (which had been found lying in Princess Lines) was originally from Farringdon's Battery as this is the only recorded historic position of this type of gun in the area.

[5] Today the battery is still in good order[1] and is listed with the Gibraltar Heritage Trust.
