Vandals have struck the Joppa Church at Mammoth Cave National Park in Kentucky/NPS

Mammoth Cave National Park officials are investigating two acts of vandalism observed at Joppa Church over the past week. On Sunday, October 28, a spray-painted two-foot by three-foot image was discovered on the church floor, and on Thursday, November 1, multiple windows were found broken or cracked.

A park release Friday did not describe the image.

"Unfortunately, incidents of vandalism at Joppa Church and the other two historic churches are not rare," said Chief Ranger Lora Peppers. "It is very disappointing that this has occurred in a building that holds such a rich history for the local communities and the park. We are actively investigating the incidents, but do not yet know if the two acts are related."

In 2015 the Joppa Church was designated as a “day-use area only” because of repeated vandalism observed at the structure. The building is listed on the National Register of Historic Places as being representative of religion and funerary practices from 1900-1949. The current structure was built in 1900, and is still the site of annual gatherings, religious services and weddings.

It is unlawful to disturb or deface natural or historic resources within the park. Perpetrators may be sentenced up to six months in jail and or fined up to $5,000. Anyone with information as to the possible identity of the vandals is encouraged to call the ranger station at 270-758-2115 or park dispatch 270-597-2729.
