The most prominent building on Slovenski trg, rumour has it that a huge Christian basilica once stood here. It quite obviously doesn’t stand here now, but in its place is a pleasant church dating back to the ninth century, although the majority of its current appearance comes from a 15th century gothic overhaul. Pretty enough from the outside, it is the interior that really delights. Pews from the 18th century, five side-altars and frescoes taking in all social classes, it is a stunning microcosm of the history of Ptuj.
