Stadtpfarrkirche, Parish church in Hartberg, Austria

Stadtpfarrkirche is a parish church in Hartberg that combines Roman-era foundations with a Romanesque tower, Gothic star rib vaulting, and Baroque interior features. The building displays a three-nave structure with a chancel and altar space, with walls and vaults showing distinct architectural layers from different periods.

The church is first documented in 1157 and sits on the remains of a Roman villa from the 2nd century that featured hypocaust heating. Excavations in 1973 uncovered parts of this ancient complex, revealing how long the site had served as a focal point for religious use.

The parish is one of the original parishes founded around 1140 by Archdeacon Reinbert von Fischau, alongside Riegersburg and Leibnitz, and the first pastor Erchenger is documented in 1157. The high altar, made in 1766, is the work of the monastic master Johann Cyriac Hackhofer and shows Saint Martin ascending to heaven. In the baptistery, a Renaissance stone font dated 1648 stands beneath a fresco of John the Baptist baptizing Jesus.

The interior is easy to access and displays all building phases at a glance, making it simple for visitors to understand the architectural evolution. Local guides Hannes Portugaller, Kerstin Hilsberg, and Sibylle Gauby offer tours on-site to explain the architectural and historical details in depth.

The west tower was once the town's own defensive tower, separate from the church and owned by the burghers, not the parish. After the 1715 fire it was rebuilt as the Baroque church tower with one of the finest spires in Styria. The east tower over the old chancel was demolished in the 1750s.
