Juraj (Giorgio) Spavento was an important 15th century builder in Venice, whom chronicler Marin Sanuto called homo di grande inzegno. He was a protomaster in construction of the Venetian bell-tower of basilica of St Marco. He participated in building of monumental Scale dei Giganti in Ducal Palace, and was involved in questions of regulation of a canal around Ponte dei Navi in Venetian arsenal. Italian historiography seems to be reluctant to stress that his birthplace was the city of Trogir.
