Holderness, US
The Chocorua Island Chapel is a non-denominational chapel located on the island of the same name on Squam Lake in Grafton County, New Hampshire, in the town of Holderness. It is an open-air place of worship, created as an extension of Camp Chocorua, the first summer youth camp in the United States.
The open-air chapel was created by the camp's first season of young boys, made entirely of boulders, trees, various island vegetation, and beach sand.
