Wentworth–Coolidge Mansion
mansion in Portsmouth, New Hampshire

Wentworth–Coolidge Mansion is a 40-room clapboard house which was built as the home, offices and working farm of colonial Governor Benning Wentworth of New Hampshire. It is located on the water at 375 Little Harbor Road, about two miles southeast of the center of Portsmouth. It is one of the few royal governors' residences to survive almost unchanged. The site is a New Hampshire state park, declared a National Historic Landmark in 1968. Today, the New Hampshire Bureau of Historic Sites manages the site with the assistance of the Wentworth-Coolidge Commission, a group of volunteer civic and business leaders appointed by the Governor.
History of the house and ownership
In 1741, the governorship of the province of New Hampshire was separated from that of the Province of Massachusetts Bay, and Benning Wentworth, son of former Lieutenant-Governor John Wentworth, was appointed its royal governor. He requested that the General Court erect a capitol in Portsmouth, but was refused.
In 1741 Wentworth rented a brick mansion in Portsmouth from his sister Sarah Wentworth Macpheadris Jaffrey, the house now known as the Warner House. That house effectually served as the governor's mansion for about seventeen years.
Wentworth petitioned the legislature to purchase the brick house as an official residence he termed a "Provincial House" in one of his petitions of April 26, 1753, but their offering price was below the owner's asking price, and the purchase was never made.
