San Leonardo, Former church in Venice, Italy.

San Leonardo is a deconsecrated church on Strada Nova in Cannaregio, rebuilt by Bernardino Maccaruzzi and completed in 1794. Its brick-red upper facade is divided into shallow rectangular panels and rises to a white stone cornice with a small pediment. The lower storey is white stone with pilasters, a central arched doorway with a dark double door, a semicircular window above, and four small relief plaques.

According to tradition, the church was founded in 1025 with support from the Crituazio family, though the first document mentioning it dates to 1089. It was re-consecrated on 4 May 1343 after a 14th-century restoration. In 1595 the bell tower collapsed, killing ten people and damaging twelve houses. Bernardino Maccaruzzi rebuilt it in 1794, and the Napoleonic decrees suppressed it in 1807.

The name comes from Saint Leonard, to whom a lay-patronage confraternity founded here in 1395 was dedicated; its income supported a second priest for the parish. The church was suppressed in 1807 under the Napoleonic decrees, stripped of altars and paintings, and used as a coal store. Today the municipality runs it as a multipurpose public hall, and it sometimes hosts exhibitions.

The building stands on Strada Nova, with its left flank set back from the old Rio San Leonardo, now filled in as Rio Terà. The side entrance opens onto the small Campo San Leonardo, still a public space. The former church now serves as a municipal multipurpose hall, so the interior is generally accessible during public events rather than as a monument.

The bell tower collapsed on 24 August 1595, damaging twelve houses and part of the church and killing ten people. The church also housed the first of Venice's Scuole Grandi, the Scuola di Santa Maria della Carità, founded here in 1260 before it moved to the Accademia site.
