This imposing structure is an architectural highlight, built in a transitional Gothic-Renaissance style, and containing an impressive art collection. Constructed around the same time as the city wall fortifications in the 14th century, the stark exterior resembles a fortress more than a religious complex. The interior contains a graceful 15th-century cloister constructed by local artisans after the designs of the Florentine architect Maso di Bartolomeo.
The large, single-naved church features some bright, modern, stained glass and a painting by Vlaho Bukovac above one of the side altars. Other priceless pieces of art are hung in rooms off the cloister, including 15th- and 16th-century works by Lovro Dobričević, Nikola Božidarević and Titian.
