The story

The Dayton Power and Light Company Mound lies inside the Killen Station power generating plant east of Wrightsville in Adams County. It is believed to have been built by the Adena, and some sources describe it as Ohio's second-largest conical burial mound, though the Enon Mound is more often given that rank. It was added to the National Register of Historic Places in 1974. It sits on industrial property, so it is not open to visitors.

The Mound Inside the Power Plant

Adams County has the Serpent Mound, and it also has a burial mound inside a power station. The mound is big enough that some sources call it the second largest cone in Ohio.

It has survived because the land around it belongs to a company that has kept it.

Behind the legend

The ranking is disputed: the Enon Mound is the one usually called Ohio's second-largest conical mound, and no measurements are given for this one in the sources available. The mound's listing and its location are documented.
