Just steps away from the hugely popular and bustling Piazza San Marco resides the 15th-century Chiesa San Zaccaria, one of Venice's most artistically dazzling and lesser known churches. Located on the site of a former, much older church, San Zaccaria looks over the quiet Campo San Zaccaria Square. Its layer-cake-like façade features a mix of styles: late Gothic on the lower levels and early Renaissance on the upper ones.
But it's the interior that is a veritable museum of noteworthy art, including one of Bellini's greatest works, La Sacra Conversazione. This magnificent altarpiece is made even better by a small donation that will illuminate the mural, taking it from impressive to altogether magical. Art by other Italian greats, from Tintoretto to Tiepolo, adorn the church's walls as well, making this relatively crowd-free spot the perfect escape while in the tourist-dense Italian city of Venice.
Note that the church closes for four hours during the middle of the day, between noon and 4 p.m. It is easily reachable by foot from central Venice, as it is located near Piazza San Marco.
