The Wonalancet Union Chapel in Tamworth, New Hampshire, is one of the most charming and photographed churches in the state, not only for its architecture, but its location with backdrop of the Sandwich Range of the White Mountains. The church was originally built around 1880 as a union chapel of multiple denominations in the Wonalancet village of town and was more vernacular in style when originally constructed. In 1896, an open tower and bell were added and the chapel saw its biggest change in 1937, when Arthur Treadwell Walden, an area resident and Klondike Gold Rush adventurer, dog breeder and participant in the first Byrd Antarctic Expedition, helped fund updates to the chapel. The present Colonial Revival appearance is following the designs of Hanover architect, Stanley Orcutt. The Wonalancet Union Chapel remains a vital institution in the village and operates sermons in the summer months.
