This is the Tip-Top House, the oldest surviving building in the summit area of Mount Washington and delivered by the state to be the oldest extant mountain-top hostelry in the world. It was built in 1853 and during that time the building’s flat roof was used to place large telescopes to create an observatory. The building stands adjacent to Mount Washington Summit (extreme right of the picture) at 6,288 feet, the tallest mountain in the northeastern United States.
