Langdon House

A National Historic Landmark, Governor John Langdon House is an exceptional Georgian mansion which George Washington “esteemed the first” in Portsmouth, New Hampshire. Its reception rooms are of a grand scale suited to ceremonial occasions and are ornamented by elaborate wood carving in the Rococo style.

John Langdon was a merchant, shipbuilder, Revolutionary War leader, signer of the United States Constitution, and three-term governor of New Hampshire. At the end of the nineteenth century, his descendants purchased the house and restored it to its eighteenth-century appearance. They added a substantial wing designed by the architectural firm of McKim, Mead, and White to house modern necessities. The house tells the story of the early colony of New Hampshire, Portsmouth’s mercantile boom, and the Colonial Revival movement.

The Governor John Langdon House is located at 143 Pleasant Street, Portsmouth, New Hampshire.
