Church Building  

12^th Century Basilica

The basilica with a mighty two-tower westwork (west-facing entrance) was built in the 12th century.

14^th Century Long Chancel (Long Choir)

The long chancel was added in the first quarter of the 14th century.

Nave and Side Aisles

The elevated central nave has clerestory windows.

The walls of the side aisle are pierced by arched windows on two floors.

Chancel 

The walls of the chancel (long choir) are supported by three-tiered buttresses.

High double lancet windows with original tracery pierce the walls at the end of the chancel.

Triple lancet windows pierce the walls of the chancel bays.

Sacristy

The sacristy is built north of the chancel.

Two-Tower Westwork

The westwork has the same width as the nave.

In the Baroque period, the Gothic pointed arch window above the west portal was replaced by a large arched window.

After the fire of 1895, it was decided to restore the towers in neo-Romanesque style. The massive double tower facade was built between 1896 and 1912, in the Rhineland Romanesque style.

There are three wall slits on each side of the west facade. The twin towers rise above the slits.

Windows on the tower face:
– two biforate windows at the top (on all four faces)
– two rounded arch windows in the middle (on three faces only)
– single biforate window at the bottom (on three faces only).

The towers are crowned by pointed gable helmets. Each tower is supported by a corner buttress.

Roman Relief Panel

A Roman relief panel depicting Minerva is attached to a pillar, north of the church.

Medieval Stained Glass on Windows  

The church inventory of medieval stained glass is of utmost importance.

Late Romanesque stained glass, which was created around 1270 to 1280, was transferred here from the Dominican Church in 1838 and installed in the north-side chancel window.

Prestigious Church Organ 

One of the most famous organs in Carinthia has been in the possession of the church, since 2000. The slider chest instrument was built by the Orgelbau Eisenbarth company from Passau. The organ has 43 registers on three manuals and a pedal.
