Wallage House & Old Dutch Parsonage Historic Sites Overview

Call on the commander in chief and follow New Jersey’s colonial colleges and founding faiths into the American Revolution at Wallace House & Old Dutch Parsonage.

Wallace House, home of a Philadelphia merchant, served as George Washington’s winter headquarters while Old Dutch Parsonage, residence of Dutch Reformed Church ministers, was home to delegates to the Provincial Congress that declared New Jersey’s independence.  

The Dutch Reformed Church in New Jersey’s Raritan River Valley constructed Old Dutch Parsonage in 1751. Here the Great Awakening preacher Rev. Johannes Frelinghuysen boarded and tutored students including his eventual successor the Rev. Jacob Rutsen Hardenbergh. From this house, Rev. Hardenbergh led the effort in 1766 to charter Queen’s College, today Rutgers, the State University of New Jersey. Dutch emigrant Dinah Van Bergh, wife in succession to both ministers, was herself a leader in New Jersey’s Dutch Reformed Church. Discover eighteenth-century New Jersey’s religious and national diversity and early leadership in American higher education at Old Dutch Parsonage.  

Philadelphia merchant John Wallace’s New Jersey country home, the largest private dwelling built in New Jersey during the Revolutionary War, served as Gen. Washington’s winter headquarters for the 1778-79 Middlebrook Cantonment. Aides-de-camp John Laurens and Alexander Hamilton conferred with the commander in chief here while Martha Washington joined her husband to host an American Indian delegation and diplomats from France and Spain. Hear the histories of women and men in slavery and freedom who composed Gen. Washington’s “military family” during the Continental Army’s most successful winter camp.

Wallace House served as George Washington’s headquarters during the Middlebrook Cantonment, the Continental Army’s 1778-79 winter camp along the Watchung Mountains in Somerset County.

Additional generals of the Continental Army stayed at historic houses still standing throughout Somerset County today. Nathanael Greene’s headquarters at Van Veghten House now holds the library and archives of the Somerset County Historical Society. Lord Stirling’s headquarters at Van Horne House is home to the Heritage Trail Association. Friends of Abraham Staats House preserve and interpret Baron Von Steuben’s headquarters in South Bound Brook.

To the north in Bedminster, Jacobus Vanderveer House & Museum preserves Henry Knox’s headquarters and shares the history of the Pluckemin Cantonment, winter camp for the Continental Army’s artillery and home to the nation’s first military academy.
