Zecca of Venice

The Palazzo della Zecca is a 16th-century building in Venice which once housed the official government mint, or offices responsible for coining money. This building, rustic and robust in its external surface, stands in stark contrast to the ornately decorated Biblioteca Marciana next door. Both buildings were designed by Jacopo Sansovino. Today, the Zecca now serves as the host of the contents of the library of the Biblioteca Marciana.
