The Mars Hill Church and cemetery are located near Ottumwa lowa. The church was built in 1850 and is said to be one of the oldest ,still operating, churches in the state. The congregation meets there once each year as the church is in a very remote and secluded location.

The area of the church and the cemetery has been the scene of much vandalism and desecration over the years and is it also said to be used by occult groups for ritual ceremonies. American Ghost Society Team Leader Nancy Napier traveled to Mars Hill in July of 1991 and reported that some evidence of occult practice did exist and she found many gravestones that were stained with rings of candle wax. The area is also well known for "UFO sightings".

Before arriving at the church and cemetery, visitors cross a narrow bridge, which has its own story. It is said that many years ago, a young woman had her baby baptized in the church and then for some reason, walked to the bridge and threw the baby into the water, drowning the baby. Legends say that on certain nights, you can hear
the sound of a scream while crossing the bridge.
