It was originally the "Baluado de S. Pedro" (St. Peter's Bastion) during the Spanish period prior to the Capture of Gibraltar in 1704 under Prince George of Hesse-Darmstadt, after whom the bastion is named. The old Spanish bastion was rebuilt and renamed by the British in 1730. In 1762, during the Seven Years' War, it was armed with two 18-pdrs and four 4-pdrs to flank the ditch in front of the Landport Gate. By 1885 the bastion's guns were all 32-pdrs.
