Kalksburger Pfarrkirche, Classic church in Liesing, Austria.

Kalksburger Pfarrkirche is a church building in the Liesing district that was constructed between 1793 and 1801 to replace an earlier chapel. The interior features a high altar painting of Saint Peter's liberation and decorative ceiling frescoes that illustrate religious stories.

A chapel on the site was elevated to a local chaplaincy in 1783, ending its dependence on the parish church of Atzgersdorf. In 1793 the old building was demolished and a Neoclassical church was built to plans by the Tyrolean architect Johann Baptist Zobel, completed in 1801. Kalksburg became an independent parish in 1805.

The church is dedicated to Saint Peter in Chains, and the high altar painting by Hubert Maurer depicts his liberation from the prison of Herod Agrippa I. Since 1803 a copy of the Magna Mater Austriae statue from the Mariazell basilica has stood in the church, a focus of local devotion.

The church sits in a residential neighborhood of Liesing that is easily reached on foot through local streets. Access to the interior depends on service times and special events, so checking ahead helps plan your visit.

The 1801 organ by Anton Pfliegler has 18 stops on two manuals and pedal, with a short octave, and retains most of its original substance. Wolfgang Karner restored it in 2024.
