Arlington Street Church is a Unitarian Universalist congregation in Boston's Back Bay, founded in 1729 as the Church of the Presbyterian Strangers. Its sanctuary holds 16 stained-glass windows made by Tiffany Studios between 1899 and 1930. Minister James Reeb, associated with the church, was killed during the 1965 Selma civil rights marches, and on May 17, 2004, the church was the site of the first state-sanctioned same-sex marriage performed in the United States.
