Hopper Gristmill Site
Built as a gristmill about 1760 by Lambartus Laroe and sold to Thomas Boggs in 1764, it had a pair of millstones. Boggs also ran a tavern in his nearby home. Owned by David Baldwin during the Revolution, the mill ground grain for American troops. Purchased after the war by Garret W. Hopper who added a sawmill. In 1832 he willed it to son William G. Hopper, a N.J. State Legislator. It operated as a mill until it burned in the late 1870’s.
Marker is on Ramapo Valley Road (U.S. 202), on the right when traveling south.
