The church is entered via a small door to the right of the main portal, overlooked by a trio of gargoyles. The interior is a treasure trove of neo-Gothic ornamentation, with a succession of pinnacled altars overlooked by exuberant stained glass windows. The interior was finished off in 1938–1942 when leading Croatian painter Mirko Rački covered the walls and ceilings with brightly coloured frescoes illustrating famous episodes from the Old and New Testaments.
