Hellerhof, Religious community center in Paudorf, Austria.

Hellerhof is a religious community center in Paudorf consisting of multiple connected buildings. The complex includes the St. Altmann parish church, the Chapel of John the Baptist, and additional spaces designed for various community functions.

The site began as Dietmarsdorf, a village founded by Archbishop Dietmar I of Salzburg (873–907); it had ten houses in the Middle Ages but was abandoned in the 14th and 15th centuries, leaving only the farm and mill. In 1477 the Counts of Hardegg gave the farm to Göttweig Abbey, and it became Dietmannshof, later Hollerhof. Abbot Gregor Heller rebuilt it in 1650–1651 with architect Mathias Canevale as a recreation residence, giving it the name Hellerhof. A fire destroyed it in 1712, and from 1991 to 1993 the new St. Altmann parish church was built.

The name Hellerhof refers to the elevated location of the site from medieval times. Today, the place continues to function as an active gathering point for religious services and community meetings throughout the year.

The facility is located along Hellerhofweg and serves as the center of the Paudorf-Göttweig parish. Visitors should check for service times and community events to best explore the grounds and buildings.

The Kienzl Museum opened in the former economic wing in 2002, named after composer Wilhelm Kienzl, who drew the plot of his opera Der Evangelimann from the 1812 fire that destroyed the Hellerhof barn. The parish library has occupied the same converted wing since 2001.
