The beauty of San Sebastiano church lies primarily in its richly decorated interior, illuminated by superb frescoes by Veronese using a complex palette of contrasting hot and cold colours and light and dark shadows. The ceiling, adorned with trompe l'oeil motifs in imitation of architectural details, features several masterpieces including Esther crowned by Ahasuerus, the Triumph of Mordecai and the Repudiation of Vasti.
