Sankt Leopold auf dem Leopoldsberg, Baroque church on Leopoldsberg hill in Döbling, Austria

Sankt Leopold auf dem Leopoldsberg is a baroque church perched on a hill in Döbling, featuring two symmetrical towers, a central cupola, and galleries encircling the interior space. The layout centers around a main hall with side chapels, demonstrating the characteristic baroque design principles of its period.

Emperor Leopold I had a chapel built on the hill in 1679 during Vienna's plague, dedicated to Margrave Leopold III, canonized in 1485. It was set on fire and plundered in 1683 during the second Turkish siege, then repaired and consecrated in 1693. Around 1720 Antonio Beduzzi expanded it into the present church; a 1945 bomb destroyed about a third, including the south tower, and reconstruction restored the baroque towers.

The church is dedicated to Saint Leopold III of Babenberg, canonised in 1485. Its name passed to the hill itself: once the church was finished, the name Kahlenberg moved to the neighbouring higher Sauberg, and the hill with the chapel became the Leopoldsberg. A venerated Marian image known as "Maria Türkenhilfe" was kept here.

Access to the church involves walking up pathways from the base of the hill, making the approach itself part of the visit. Following extensive restoration work completed in 2018, the interior is open to visitors and displays the architectural details in their restored state.

The 1797/98 high altar by sculptor Adam Vogl carries the name of God carved into its gloriole, a practice of the period also seen in Vienna's Karlskirche. The original high altar had disappeared during the church's closure in 1782.
