The church is a three-nave Basilica with a high cross-vaulted ceiling in the west tower. On the north and south façade 4 times over are ever-alternating round arched arcades, each with a large rectangular window. In the central aisle of the tower, three high, round, arched arcades are on each side except the eastern side, where the tower joins the Basilica; at each of the four points there are three round-arched windows. The choir section is polygonal; at the north and south ends are small stair towers with pointed roofs. The design of the dividing inner-wall ("zweizonige") exhibits the round-arched arcade design typical of Roman-Gothic style.
