The Greek Orthodox Cathedral of the Annunciation stands at the corner of Maryland Avenue and West Preston Street in Charm City. Designed by the prolific Charles E. Cassell, the amphitheatrical building is a unique mixture of architectural practices. Built in 1889, the structure was originally occupied by the Associate Congregational Church. In 1937 the Greek Orthodox community purchased the building for its growing congregation. Cassell also designed the First Church of Christ, Scientists and the Stafford Hotel.
