Many believe that St. Patrick brought the Celtic cross to Ireland. Others believe that it was St. Columba or St. Declan. Whomever introduced it, many believe that its configuration is based on strength of design. The circle strengthens the cross beams, preventing, or at least delaying, destruction by the elements over time.
This cross is in the Labbamologga Cemetery in County Cork, Ireland.
