St Mark’s Square (Trg svetog Marka) constitutes the heart of the Upper Town, having formerly served as the main market square of the settlement of Gradec. Dominating the square is the 13th-century Church of St Mark, a three-isled Romanesque church which still retains much of its original hape. The Gothic arched ceiling and the sanctuary were added in the late 14th century, along with the fifteen statues that stand in iches above the southern portal. Some of the statues were made by masters from the Parler workshop in Prague in around 1420.
