San Giovanni dei Lebbrosi

San Giovanni dei Lebbrosi, a 12th-century church in Palermo, Italy, exemplifies the architectural fusion of Norman and Arab influences during the Norman conquest. Originally attached to a leprosarium founded by Robert Guiscard and Roger I de Hauteville in 1071, the structure features austere, massive solidity and transenna windows, reflecting strong Arabic stylistic elements. Although scarce documentation complicates precise dating, historical records suggest its completion well after Palermo's conquest, with a leprosarium added by Roger II in 1119 to honor his half-brother Geoffrey, who died from leprosy. Over time, the church and hospital were managed by various religious orders, including the Teutonic knights. The study highlights the cultural synthesis of Norman-Arab architecture while emphasizing the historical significance of the site's association with leprosy care.
