This is the top spire of a monument at the De Soto National Memorial that is dedicated to the first communion celebrated by De Soto and his approximately 700 men in May of 1539. It is likely the first communion service in what is now the United States. There were 17 priests among the solders and adventurers and they played an important role during the 4 year four thousand mile march through the southeast from Florida to Virginia to Tennessee and on to Texas.
