National Harmony Memorial Park is a private, secular cemetery located at 7101 Sheriff Road in Landover, Maryland, in the United States.

Washington businessman Louis H. Bell owned 107.5-acre (435,000 m2) Forest Lawn Cemetery on Sheriff Road in Landover, Maryland.

The District of Columbia Department of Health had to draft and win approval of a whole new set of regulations to govern the relocations.

[5] However, there were hundreds of graves moved every day; although it is seldom mentioned, many were just put in an unmarked mass site.

[1] The headstones were sold as scrap and used to secure the riverbank of the Stuart Plantation, a 1400 acre conservation easement site on the banks of the Potomac in King George County, Virginia.

A nonprofit organization will reclaim as many of the headstones as possible and send them to National Harmony, and related memorial markers will be placed in both Maryland and Virginia.

[10] Stewart Enterprises, a company based in New Orleans, Louisiana, purchased National Harmony Memorial Park in 1998.

For information about them see Columbian Harmony Cemetery; note that the exact location of the relocated remains of any particular individual is unknown.
