Practically more a museum than a church, San Zaccaria bears a striking Renaissance facade, with central and upper portions representing some of Mauro Codussi's best work. Most of the church was 14th-century Gothic, with its facade completed in 1515, some years after Codussi's death in 1504, and it retains the proportions of the rest of the essentially Gothic structure. Inside is one of the great treasures of Venice, Giovanni Bellini's celebrated altarpiece, La Sacra Conversazione, easily recognizable in the left nave. Completed in 1505, when the artist was 75, it shows Bellini's ability to incorporate the esthetics of the High Renaissance into his work. It bears a closer resemblance to the contemporary works of Leonardo (it dates from approximately the same time as the Mona Lisa) than it does to much of Bellini's early work. The Cappella di San Tarasio displays frescoes by Tuscan Renaissance artists Andrea del Castagno (1423–57) and Francesco da Faenza (circa 1400–51). Castagno's frescoes (1442) are considered the earliest examples of Renaissance painting in Venice. The three outstanding Gothic polyptychs attributed to Antonio Vivarini earned it the nickname "Golden Chapel."
