Venice's cosmopolitan nature is evident in Castello, where Turkish merchants, Armenian clerics and Balkan and Slavic labourers were considered essential to Venetian commerce and society. This 15th-century religious confraternity headquarters is dedicated to favourite Slavic saints George, Tryphone and Jerome of Dalmatia, whose lives are captured with precision and glowing, early-Renaissance grace by 15th-century master Vittore Carpaccio.
