At Lille Sjørup Sø on the banks of the lake lies the foundation of a Norman church. The church ruins where unearthed when the golf courses at Gatten were being extended in 1989.
When the church was pulled down the stones were used in among places for the church of Ulstrup nearby. The yard around the ruins holds 1.300 graves.
Up to 1850 the wall around the churchyard could still be made out.
Every summer an open service is held in the church ruins.
