The Trinity Church building in New Castle, PA, has historical significance and is associated with the Trinity Episcopal Church established in April 1848. The Romanesque Revival-style building was designed by Youngstown-based architect C. H. Owsley. The first services in the new Trinity Episcopal Church building were held in the basement on March 15, 1903, and the completed church was dedicated on Easter Sunday, April 12, 1903. Over the years, the church acquired additional property for expansion, including land from the descendants of pioneer Henry Falls.
