Portsmouth, NH 03801
Wentworth-Coolidge Mansion Historic Site is the former home of New Hampshire's first royal governor, Benning Wentworth, who served in office from 1741 to 1767. The rambling 40-room mansion which overlooks Little Harbor, is one of the most outstanding homes remaining of the colonial era. Its stateliness and impressive interior and furnishings reflect aristocratic life in Portsmouth in the 1700s.
The Mansion reflects five distinct periods of architecture. The extraordinary skill of New Hampshire's eighteenth century craftsmen is exhibited in the intricate hand-carved mantelpiece. The council chamber and the spy closet reveal details about daily life and government during the colonial period. Purple lilacs, descendants of the first European stock imported by Wentworth, decorate the grounds.
Little Harbor Loop Trail: Be sure to go for a stroll on this 1.5 mile waterside path that connects the Wentworth-Coolidge Mansion Historic Site, Creek Farm and Portsmouth Conservation Land. Free parking and trail access are available at the Wentworth-Coolidge Mansion Historic Site.
