Completed at the behest of Admiral George of Antioch in 1131/2, the Admiral’s Bridge connected Palermo with the gardens beyond the Oreto River. Made of stone with regular calcarenite ashlars, it has two symmetrical ramps supported by seven bays with pointed arches and recessed rings. Each arch is punctuated by piers with pointed openings, strategically placed to balance the weight and reduce the thrust of the river flood.
