St. Nicholas Greek Orthodox Cathedral was built in 1923, but the Greek Orthodox faithful has worshipped in temporary quarters since 1906. The three previous sites were the second floor of a building at 512 Court Place in Downtown Pittsburgh, a church building at 95 Fullerton Street, Uptown, and another second floor hall at 645 Sixth Avenue. After a merger with Annunciation Church in September, 1918, it was agreed that worshipers would unite under the name "The Greek Community of Allegheny County-St Nicholas Greek Orthodox Church". The Church was founded to "set firm the foundations for future perpetuation of our faith and heritage by establishing Greek and Sunday schools for teaching Greek Orthodoxy and the Greek language." St. Nicholas is the oldest and largest parish in the Sixth Archdiocesan District, and as it serves as the heart of Greek Orthodoxy in this area, it assumes a unique responsibility and duty to provide leadership in religious education, youth work, philanthropy, conferences and other worthwhile endeavors.
