Kirche Hörersdorf, Gemeinde Mistelbach, Catholic parish church in Hörersdorf, Mistelbach, Austria

Kirche Hörersdorf is a church with a Baroque nave and a recessed Gothic choir with a five-eighth close under a shared saddle roof. The three-storey Gothic tower stands almost entirely within the south-west corner of the nave, with a chamfered ground floor, corner quoins, slit windows, a Baroque bell storey and a 19th-century tent roof. The choir has stepped buttresses and pointed-arch windows, one of which is walled up in the east end.

A vicariate existed before 1300, and in 1661 the parish was documented as incorporated into the Barnabite college of Mistelbach. The Gothic nave dates from the 14th century and was remodelled in Baroque style around 1700. The bell storey and the tent roof of the Gothic tower were added in the 19th century.

The parish is dedicated to Saint Oswald, whose painting above the high altar dates from around 1800. On the triumphal arch stands a Baroque carved figure of Saint John Nepomuk, and side consoles carry Saints Rochus and Sebastian. A Romanesque sandstone relief of the Crowned Christ, once built into the cemetery wall, is kept in storage.

The church stands on a hill east of Hörersdorf, in the municipality of Mistelbach. The churchyard is enclosed by a wall, and a staircase on the north side of the west front leads up to the gallery. A Baroque gravestone with a Crucifixion scene from around 1750 stands in the cemetery.

The choir's keystone bears a relief of the Lamb of God, a 14th-century carving. The organ was built by Franz Reusch around 1850/1860. A Romanesque sandstone relief of the Crowned Christ on the Cross, once walled into the cemetery wall, is now kept in storage.
