On the busy Mercerie, the church of San Zulian (or Giuliano) provides a refuge from the crowded alleys. Its interior features gilded woodwork, 16th and 17th century paintings, and sculptures. The central panel of the frescoed ceiling, portrays The Apotheosis of St Julian, painted in 1585 by Palma di Giovane.
The 16th century church façade was designed by Sansovino and financed by the rich, and immodest physician, Tommaso Rangone. His bronze statue, surrounded by books, stands out against the white Istrian walls.
