The Winchester Memorial Church, also known as the New Hampshire Conservatory of Music and the Arts, is a historic civic building in the center of Winchester, New Hampshire, United States. Built in 1912, it is a prominent local example of Colonial Revival architecture. It replaced a meeting house that was the location of the Winchester Profession, a key development in the history of Unitarian Universalism. The building was listed on the National Register of Historic Places in 1980. It was acquired in 2006 by the Universalist Heritage Foundation as a memorial to the site's role in Universalist history.
