This is the only known photograph of the interior of the former amphitheatre that was part of the Chautauqua grounds in Niagara-on-the-Lake. The Chautauqua movement was a semi-religious social and cultural phenomenon that swept through North America in the late 1800s. This amphitheatre was built to seat over 3,000 people and was where guests could enjoy religious and educational courses as well as music concerts. It was located within the boundary of Circle Street in the current Chautauqua community.
