The two largest Gothic churches to remain largely unaltered are those of the main mendicant orders; both are designed to provide large open spaces for star preachers to reach big congregations. These orders were controlled from the Italian mainland, and their original architecture mostly reflected broader Italian styles developed by each order elsewhere, and so represented a novelty in Venice. Both became home to numerous important wall tombs inside, which has probably prevented the interiors from having Baroque makeovers, as has happened elsewhere.
