Another pinner said: Celtic Cross: Represent the bridge or the passage between heaven and earth. The circle in the ringed cross signifies infinity and eternal spiritual love. Celtic Spirituality: love of nature and a passion for the wild and elemental as a reminder of God's gift. -love and respect for art and poetry. -love and respect for the great stories and "higher learning" A mandate for hospitality. Emphasis on family and kinship ties. Feels right to me!
This is a castle in Ireland. As opposed to the beautiful continental castles, this one is rather austere and rough. Ireland wasn't invaded by the Normans until the 11th century, and it was only then they learned to build stone castles.
