The church is a five-naved, Gothic hall church made out of local travertine.
The central nave is twice as wide as the side aisles.
On the western end of the church are the three steeples: two side spires, roughly 42 m (137 ft 10 in) high, and the main, 86.7 m (284 ft 5 in) high central spire.
The towers are octagonal, built on a square base and foundation.
On the eastern side are three choirs, a large central choir flanked by two smaller ones.
Typical of the Gothic style, the central choir is high and narrow.
The northern side choir was a baptismal chapel dedicated to Saint Nicholas, while the sacristy was located under the southern one.

The interior is divided into four rows by five tall, narrow columns.
In the Medieval period, the gallery housed a library (which was common for larger churches to have at the time).
The transept is as wide as the central nave.
The southern portal of the transept serves as the main entrance to the church and is typical of the Gothic style.
