This monument is the product of a project led by Joe McGlynn to honor the Irish Americans in the St. Louis area and their contributions to the area. The monument itself is an 16.5' tall granite celtic high cross by sculptor John Scott within a reflecting pool at St. John, the Apostle and Evangelist Church - the oldest remaining Irish parish in St. Louis.
