On the corner of Dalmatinskog Sabora Street and Hrvoje Vukchich Hrvatinich Street near the market, the church of St. Andrew has a facade from the 17th century, but other parts date from 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 from the 12th century and are used today as exhibition spaces. Church of St. Peter the Great was originally an oratory from the 5th century, and represents the oldest found cult object of early Christian culture within the walls of Roman Zadar. The church of St. Petra was built after the square was added to the oratory on its eastern side, and it was turned into a two-nave church.
