The basilica is on the Egyptian Cross plan, with a nave covered by spans and a transept, according to type favoured by the
Mendicant Orders, which needed spaces capable to house large crowds of faithful. The current interior looks rather sober after a fire in 1655 and the restoration of 1885–1892, when many of the Baroque altars were demolished (some of the paintings has been however returned in recent times). The neo-Gothic façade, flanked by the 1763 campanile, dates to the early 20th century. The medieval marble decoration and the 15th century portal were removed in that occasion. == Interior ==
