Celtic crosses in carved stone exist right across the lands frequented by Celtic saints. In Ireland you have the high crosses which stand over ten feet tall. Some great examples survive at the monastery of Clonmacnoise, Ireland and St Illtud's Church, Llantwit Major, Wales. In Cornwall, you'll find Celtic crosses on hidden byways, or lonely lanes. There are many remaining in church yards or at crossroads. Some are in amazing condition, others weathered and almost unrecognisable. They were used as way markers but also to share the gospel story. Many are breath-taking in their craftsmanship.
