Built in 1763, it is notable for its fine Georgian finishes, and for its associations with leading political and economic figures of 18th and 19th-century Portsmouth.

The entrance at the center is topped by a half-round transom window, and is sheltered by a Federal-period portico with a modillioned cornice and hip roof surrounded by a low balustrade.

Wentworth's son John was appointed Royal Governor of New Hampshire in 1767, and occupied the house from then until his departure on the eve of the American Revolutionary War in 1775.

Mark Wentworth maintained ownership of the house during the first part of this period, and transferred the property to his daughter Anna Fisher in 1770.

[2] In the early 1900s Wentworth descendants adapted the property for use as an elder care facility, a role it continues to serve today.
