On the corner of Ulica Dalmatinskog Sabora and Ulica Hrvoja Vukčića Hrvatinića (near the market), the simple frontage of St Andrew's has an unremarkable 17th century facade, but other parts date back to the 5th and 6th centuries. Through the apse you enter the very unusual church of St Peter the Elder, also from the early Middle Ages. Both contain fragments of ancient frescoes, and the atmospheric interiors are now used as exhibition spaces.
