The Arlington Street Church is a Unitarian Universalist church across from the Public Garden in Boston, Massachusetts. Because of its geographic prominence and the notable ministers who have served the congregation, the church is considered to be among the most historically important in Unitarian Universalism. Completed in 1861, it was designed by Arthur Gilman and Gridley James Fox Bryant to resemble James Gibbs' St. Martin-in-the-Fields in London. The main sanctuary space has 16 large-scale stained-glass windows installed by Tiffany Studios from 1899 to 1930.
