The first documented mention of the parish church dates from 1147. The late Gothic building was renewed after the great fire of 1642 and the tower was raised to 55m. In the two-bay extension in the northern corner of the tower is a life-size baroque Oilberg group with the associated scenic wall painting (c. 1650). The south wall is particularly decoratively painted with coats of arms and the clock with a Renaissance dial; the fresco of the sundial bears the year 1622. The parish church of Grein is dedicated to St. Giles. The altarpiece created by Bartolomeo Altamonte in 1749 shows St. Giles with the hind ("hind") and is framed by a sweeping baroque structure.

This chapel is not an ordinary place of worship, but a monument to one of the largest hydraulic engineering projects in Austrian history. The chapel stands in a historically extremely exciting place. Formerly, the notorious island of Hausstein was located exactly here - in the middle of the stream. The island divided the Danube into two arms and, together with other rocks (such as the "Wirbel"), caused the most dangerous currents in the entire Danube. Countless ships were wrecked here. Between 1853 and 1866, Emperor Franz Joseph I had the rocky island of Hausstein and other obstacles blown away to make the Danube safe for modern shipping. The chapel was built on the bank after the completion of these works. It commemorates the taming of the river.

The church directly on the town square of Grein is the town parish church dedicated to Saint Giles. It is not only an architectural eye-catcher, but also holds some exciting stories. The church is essentially a late Gothic building from the 15th century. When you go inside, you will see the magnificent ribbed vault of the three-aisled hall. Like so many churches in Austria, it was later Baroque-style. Especially the high altar (around 1749) is a real showpiece. The "walled-up" tower: A curious story surrounds the tower entrance. This was "desecrated" around 1600 after the murder of a young girl and then walled up for centuries. It was not reopened until 2004 and now serves as a barrier-free access.
