Glen House is the name of a series of grand resorts and hotels, dating back to 1852, in Pinkham Notch very near Mount Washington in the White Mountains of New Hampshire, USA.
John Bellows converted a farmhouse into a hotel the same year and then sold it in April 1852 to J. M. Thompson, who renamed it the Glen House and finished work on its rooms.
Guests could visit Mount Washington on the newly opened Carriage Road (now the Mount Washington Auto Road) to its summit, visit other natural attractions in the area, or recreate in the hotel's game rooms, parlors, library, listen to an orchestra, dance, play lawn tennis, fish, play croquet, hike, horseback ride, enjoy a guided carriage ride, or take in a theater show.
John P. Soule, G. W. Woodward, Nathan W. Pease, and the Kilburn Brothers also captured stereoscopic images from the area, including mountain landscapes and other scenery as well as some of the grand hotel and its interior spaces.
Property ownership was subsequently acquired by the Libby family of Gorham who converted the existing servant's quarters into the third Glen House, a 40-room hotel, that was also destroyed by fire in 1924.
