Our History

​Our forefathers established the Church in 1954, purchasing a former Bulgarian Church, which served as our spiritual home until 1997. In October 1997, His Holiness Catholicos Aram I of the Great House of Cilicia consecrated the current St. Gregory Church that is located at 1014 W. Pontoon Road in Granite City. Our parishioner and member base stretches across the entire Metro St. Louis area and we welcome all to worship with us. Adjacent to the Church is St. Gregory Armenian Community Center which sits on 5 acres and was opened in 1986.
