In 1865, a society was formed to establish a new Congregational church in the the north section of Springfield. The cornerstone for the new Memorial Congregational Church was laid on July 18, 1867. The church, constructed on a knoll at Plainfield and North Main Streets (an area now called Memorial Square), was designed by Richard Upjohn. The granite used for the building was the gift of Mr. William Flint of Monson. The church was dedicated on June 3, 1869. In 1940, Memorial Congregational Church merged with Hope Congregational Church (Hope Church merged with Faith Congregational Church in 1977). The former Memorial Congregational Church building was sold to the Hellenic Religious Building Fund Corporation to become St. George’s Greek Orthodox Church. A brick house on Auburn Street had become the church’s first building in 1907. The church moved to Patton Street in 1919. In 1977, one-third of the church community left to form the new St. Luke parish in East Longmeadow. St. George Church then became known as St. George Greek Orthodox Cathedral.
