Celtic crosses are distinctive stone structures that combine a traditional Christian cross with a circular ring surrounding the intersection. Originating in Ireland and other parts of Britain during the early Middle Ages, these crosses often feature intricate carvings and designs that reflect Celtic art and symbolism. They served both as religious markers and as monuments to commemorate the deceased. Typically made from granite or limestone, Celtic crosses can be found in various sizes, from small roadside markers to large, elaborate monuments in graveyards. The circular ring is believed to symbolize eternity, while the detailed carvings often depict biblical scenes or Celtic knots, showcasing the rich cultural heritage of the regions where they are found.
