One of the oldest and most intact mill villages in the U.S. state of Maryland, Jerusalem is located in Harford County, along the Little Gunpowder Falls River.

Evidence suggests that David Lee and several of his Quaker neighbors carved black walnut stocks and assembled rifles for the Continental army in the gunshop that stands behind the gristmill.

[2] The historic buildings are being restored and preserved by Friends of Jerusalem Mill, an all-volunteer, non-profit, public charity, which has leased the village from the state of Maryland since 1986.

Events include a living history program, concerts by the falls, jousting tournaments, vintage baseball, First Responders' Day, and a lot more.
