After the destructive Great Siege, the town was almost entirely rebuilt. Giovanni Maria Boschetti, who arrived in Gibraltar in 1784 as a 25-year-old from Milan, where he is thought to have been a stonemason or engineer, built the Victualling Yard (completed in 1812) and many other buildings. Boschetti is regarded as having been responsible for setting the old town's style, described by Claire Montado, chief executive of the Gibraltar Heritage Trust, as "military-ordnance-style arched doorways, Italianate stucco relief, Genoese shutters, English Regency ironwork balconies, Spanish stained glass and Georgian sash and casement windows."
