The Abbendorf village church, located in the Abbendorf district of the village of Diesdorf, is a significant example of neo-Gothic brick architecture. The current church building was constructed in 1875. Parts of the medieval predecessor, including the choir and its end, were retained, raised, and fitted with new windows.
The church interior features impressive cross-ribbed vaults, whose pear-shaped ribs can be seen in both the choir and the nave. The pointed triumphal arch dates back to the Middle Ages. Particularly outstanding is the carved altar from the late 15th century, which was restored in 1971. Its shrine depicts a crescent-shaped Madonna, flanked by four reliefs from the life of the Virgin Mary, while the wings depict twelve apostles.
Other valuable works of art in the church include a small Vesperbild (Vesper picture), a statue of St. Christopher from the early 16th century, and a wooden pulpit from 1734. The sandstone baptismal font, the organ, and the pews date from the 19th century. The listed church is an important example of regional sacred architecture.
