Pfarrkirche Stammersdorf, Roman Catholic parish church in Floridsdorf, Austria

Pfarrkirche Stammersdorf is a Roman Catholic parish church dedicated to Saint Nicholas, set slightly elevated on a spur of the Bisamberg above Stammersdorfer Straße. The late Romanesque nave is narrow and high, with cross-arm side chapels, a curved west gable and a massive square east tower with buttresses and a helm of 1800. The former choir, a late Gothic polygonal structure, now serves as the sacristy.

The Romanesque church was built in the 12th century as a fortified church linked to a castle on a spur of the Bisamberg. In 1429 it is first recorded as a filial church of Kleinengersdorf, and in 1540 the Vornbach monastery handed that parish to the Schottenstift, after which Stammersdorf became independent. Matthias Corvinus's invasion in 1484, the 1683 Turkish siege and the 1850 village fire caused damage; the tower helm dates from 1800.

The church is dedicated to Saint Nicholas, and his legend is painted beneath the organ gallery, alongside Saint Cecilia and King David. The wall paintings were made in 1868 by Josef Kastner and his daughters, following the earlier Baroque decoration; the choir shows the Annunciation with Saint Benedict and Saint Scholastica, recalling the Schottenstift.

The church stands slightly elevated behind a small forecourt, the former cemetery closed in 1844, north of Stammersdorfer Straße; Liebleitnergasse links it southward with the lens-shaped village green. Two gabled portal porches open on the south side, the western one cross-vaulted. Look for the three classicist wall epitaphs there: Friedrich Graf Kinsky († 1794), Francisca Esterhazy († 1801) and Anna Dangl († 1821).

The parish belonged to the Bavarian monastery of Vornbach until 1540, when a shortage of priests led it to be handed to the Schottenstift in Vienna. Because of that link, the choir murals show Benedictine motifs, including Saint Benedict and Saint Scholastica above the windows.
