The Baroque church dedicated to St. Blaise stands prominently on Luža Square at the eastern end of the Stradun, built between 1706 and 1717 by the Venetian architect Marino Gropelli after its predecessor was destroyed in a fire in 1706. The exterior is richer and more theatrical than most buildings in Dubrovnik's restrained Baroque, with pilasters, a dome, and an ornamental facade facing the square.
Inside, the altars are decorated with 18th-century painting and the treasury holds a silver-gilt statue of St. Blaise dating from the 15th century — one of the oldest surviving representations of the city's patron saint. The church is active and services are held regularly. The feast of St. Blaise on 3 February is the largest annual celebration in Dubrovnik, with processions through the old town.
