Constructed in 1859, it was the successor to the smaller Harmoneon Cemetery in downtown Washington. All graves in the cemetery were moved to National Harmony Memorial Park in Landover, Maryland, in 1959. The cemetery site was sold to developers, and a portion used for the Rhode Island Avenue – Brentwood Washington Metro station.
