Built in an instantly recognisable Baroque style, this 16th-century masterpiece dominates Prešernov Trg like a large pink birthday cake. Part of a larger complex that includes the adjoining Franciscan Monastery, if you’re lucky enough to find the doors unlocked expect a few treats inside including Robba’s 18th-century altar, some charming frescoes dating from 100 years or so later and a chapel notable for containing a cross designed by none other than Jože Plečnik. For those who don’t appreciate the finer points of ecclesiastic architecture, the front steps do at least provide a nice place to sit and watch the world go by on a gloriously sunny day.
