The small parish church in Kleinzell was built in the 14th Century. It is stately perched on top of the hill. Fifty-six stairs lead up to the parish built in honor of Mary's Assumption into heaven. The wooden altar was created by Linz sculptor Ludwig Linzinger in 1897 as part of the neo-Gothic renovations. The relief shows the Annunciation of the Blessed Virgin Mary and the announcement made by the Angel Gabriel saying that she would conceive and become the mother of Jesus. Cross ribbed ceiling. Artistically carved, wooden Stations of the Cross hang on the walls. The oldest bell in the district tolls every Saturday at noon as a reminder that once sirens blared warning the villagers of impending bomb attacks. The refurbished chamber organ was built by Ignaz Gatto "The Elder" in AD 1750.
