Pfarrkirche zur Allerheiligsten Dreifaltigkeit, Parish church in Rudolfsheim-Fünfhaus, Austria

The Pfarrkirche zur Allerheiligsten Dreifaltigkeit is a parish church on Reindorfgasse featuring traditional architectural design from the late 18th century. Its interior contains religious artworks and the building is protected as a historical monument.

The parish was planned from 1783 as a Josephinian foundation, and the church was built between 1787 and 1789 to plans by Johann Michael Adelpodinger. A north side aisle and sacristy were added in 1861, and the building was restored from 1979 to 1981. When the Fünfhaus parish was dissolved on 30 June 2016, its territory was assigned to Reindorf.

The parish was founded under Joseph II from 1783, and the church is dedicated to the Holy Trinity. The high altar, made around 1788, holds a Trinity painting by Franz Anton Maulbertsch, restored in 1927. The two side altarpieces, painted by Martino Altomonte in 1713, came from the former Augustinian canons' church of St. Dorothea in Vienna's first district.

The church is easily accessible by public transportation, with several bus and tram stops near Reindorfgasse. Visitors should be aware that services occur at set times, though entering outside these hours may be possible.
