Mark Wentworth House, historic house in Portsmouth, New Hampshire, United States

The Mark Wentworth House is a mansion built in 1763 on Pleasant Street in Portsmouth, designed in the Georgian style with fine wooden finishes and a symmetrical five-section facade. The structure features a hip roof, decorative cornice with modillions, and well-preserved interior elements including fireplaces and original wallpaper with paper-mâché borders imported in 1774.

The house was built in 1763 by merchant Henry Appleton and soon passed to Mark Hunking Wentworth, whose son John became Royal Governor of New Hampshire in 1767. After John's departure at the start of the American Revolution, the property changed ownership several times until Ebenezer Wentworth repurchased it in 1810.

The house takes its name from Mark Hunking Wentworth, the wealthy merchant who bought it in 1764, not from a later owner. His son John, Royal Governor of New Hampshire from 1767, lived here until he left in 1775 at the start of the American Revolution. In the early 1900s Wentworth descendants turned the property into an elder care facility, a use it still serves.

The house is located near downtown Portsmouth and is easily accessible on foot to view its historic exterior. Those interested in tours or more details should contact Wentworth Senior Living, which may offer visits depending on availability.

The house was built in 1763 by merchant Henry Appleton, who sold it the next year to Mark Hunking Wentworth, one of New Hampshire's wealthiest merchants and landowners. His son John, appointed Royal Governor of New Hampshire in 1767, lived here until he left on the eve of the American Revolution in 1775. The property was sold out of the family in 1797 and bought back by Ebenezer Wentworth in 1810.
