The main apse has retained its integrity and as such is an example of mid-12th century architecture.
A great number of Hungarian churches are characterized by this structure when the rotunda serves as the main apse of the later romanesque church.
Two pillars aligned with the points where the side apses merges into the main apse divide the altar into a prothesis and a diaconicon.
It is a domed church with one main apse, two small apses and four columns.
At the east end the main apse is decorated by two rows of free-standing columns.
The choir and transepts are immensely lofty with the main apse rising to the full height of the building but the nave is considerably lower.
The nave ends with the main apse, which is flanked by two smaller ones.
The south-east orientation of the main apse allowed the erection of the mihrab inside it.
The church today has a main apse flanked by two subsidiary apses.
The main apse is pentagonal.
