In a large-scale act of vandalism in the St-Cyriak-Kirche in Dielheim, discovered on the 22nd of June, the glass of a candlestick was broken as were numerous candles, the contents of a first-aid kit were scattered on the floor, a holy water font was emptied and self-painted pictures of the first communion soaked with water. The damage is estimated to be around 3000 euros. This current case of vandalism has moved the parish council to go to the police and limit the opening hours of the church. The church has seen smaller acts of vandalism before, including broken windows or candles, but something of this scale hasn't occurred since 2017.
In 2017, the organ was badly damaged by vandals, numerous pipes were bent or partly trampled on.
