Back: Casemates Square originally formed part of the Lower Ward of the Moorish Castle. It was the heart of La Barcina, part of the 15th century Spanish city, at the confluence of the roads leading to the Land and Sea Gates to Gibraltar. The British built a large Barracks at this strategic point, Casemates Barracks, that gave the square its present name. It is now a gastronomic, shopping and leisure hub.

Back: The King's Bastion stands at the centre of the medieval seawall that protected the old City. It was fortified by General Boyd (who is buried in the Bastion) in 1773 in time for it to play a key role in the defence of Gibraltar during the Great Siege. Gibraltar's first electricity generating plant was sited in the courtyard of the Bastion. The Generating Station was demolished to give way to today's leisure centre, a stunning innovative use for a historical military fortification.
