A National Historic Landmark
A visit to Langdon House takes you back to post-Revolutionary America and the early days of the republic. A three-term governor of New Hampshire, Langdon was also a Revolutionary leader, a signer of the United States Constitution, and a friend of George Washington, who visited the house in 1789.
The house features a vast central hall, elaborate carved mantelpieces, a dining room designed by Stanford White, and a large garden with perennial beds, a 160-foot-long rose and grape arbor, and a pavilion. Admission includes both a house tour and access to a rotating series of exhibitions.
