The Frari is the nickname for the church if Santa Maria Gloriosa dei Frari, and "frari' is the Venetian form of "frati" for the brothers of the Franciscan order.
It's one of the must-sees of Venice. Filled with art, magnificent tombs, and stunning architecture, it's one of my favorite churches in this city of splendid churches.
Check out this link to a site with some excellent photos of the interior and exterior of the Frari, with an added bonus of a restaurant recommendation.
And if you go, take time to marvel at Giovanni Bellini's beautiful altarpiece (above), Titian's transcendent Assumption, and Donnatello's sculpture of John the Baptist, and the pyramid monument to Canova.
Admission is only 2.50 euro and it's very near the San Toma' vaporetto stop or a pleasant walk from the Rialto Bridge.
