Pfarrkirche Stein an der Donau, Parish church in Krems, Austria.

Pfarrkirche Stein an der Donau is a Roman Catholic church on Steiner Landstraße in Krems, at the foot of the path up to the Frauenbergkirche. Its three-aisled, four-bay late Gothic stepped hall has a net-ribbed vault in the nave and cross-ribbed vaults in the narrower aisles, with a two-bay choir ending in a five-eighth close. The west tower carries a Baroque bell storey with corner vases and an onion dome with lantern.

The church is documented in the 12th century, with parish rights recorded from 1263; it remained a vicariate church of Krems until the end of the 16th century. The Gothic choir dates from the second half of the 14th century and the late Gothic stepped hall from the second half of the 15th century. It was baroquized in the 18th century, regothicized around 1900 and restored in 1951.

The church is dedicated to St. Nicholas, and its parish rights were documented from 1263; until the end of the 16th century it remained a vicariate church of Krems. Inside, the three-aisled stepped hall has eight-sided pillars and a net-ribbed vault in the nave, while the narrower side aisles carry relief-carved coats of arms on their keystones to the north.

The church is located on Steiner Landstraße and is easily accessible on foot from the town center. Visitors should remember this is an active place of worship, so respectful behavior and quiet conduct are important.

The organ, built in 1481 by Anton Preysinger with 23 registers, was restored by Gregor Hradetzky in 1975. Many gravestones are set into the church's outer walls, and the northern pointed-arch portal has been walled up.
