Tip-Top House (Mt. Washington NH)

Wikipedia says: The Tip-Top House is a historic former hotel in Mount Washington State Park in Sargent’s Purchase, New Hampshire, United States. Built in 1853, it is the oldest surviving building in the summit area of Mount Washington, and is believed by the state to be the oldest extant mountain-top hostelry in the world.

The Tip-Top House stands directly adjacent to the summit of Mount Washington, at 6,288 feet (1,917 m) the tallest mountain in the northeastern United States. It is located on the southwest side of the summit.

It is a roughly rectangular structure, 1-1/2 stories in height, with walls of rough-cut granite. The stones are mortared together, but the joints are set deep and the mortar is barely discernible. The main entrance is set off-center on the southern short end, in a simple rectangular opening. The sides have rectangular window openings.
