Built in 1750 by New Hampshire?s first royal governor, Benning Wentworth, the Wentworth-Coolidge Mansion was the statesman?s way of making amends with the lack of a capitol in his area of responsibility. The mansion has forty rooms and is placed in a 100-acre lot, designed to function as a farm and a council chamber.

The Wentworth-Coolidge Mansion is known as one of the few remaining royal governor residences in the country that has been unchanged massively, despite being acquired by another owner in the 1800s. In 1968, it was declared as a National Historic Landmark. It now functions as a state park under the care of the state government through New Hampshire Bureau of Historic with the aid of the Wentworth-Coolidge Commission.
