Plaques at the house read: "Hendrik Van Allen House - Located on Ramapo Valley Road, key military highway for troops and supply units during the Revolutionary War. This building served as General George Washington's Headquarters on July 14, 1777 and as the Bergen County Court House in 1778 - 1779." [1]
"This Dutch Colonial farmhouse was built by Hendrick Van Allen before the Revolutionary War on a farm that consisted of over 200 acres. General George Washington used this house as his headquarters on July 14-15, 1777, when he moved his troops over 'extremely deep and miry roads' from Morristown, New Jersey to Smith's Clove, New York."
