Celtic Crosses are distinctive stone crosses that originated in early medieval Ireland and Britain. They typically feature a cross with a circle around the intersection, symbolizing the connection between the earthly and the divine. These crosses often display intricate carvings, depicting biblical scenes, knotwork, and other designs that reflect Celtic art and culture. The use of Celtic Crosses was prevalent from the 5th century onward, serving both as religious symbols and as markers for graves. Many of these crosses can still be found in churchyards and historical sites, showcasing the rich heritage of Celtic Christianity and its influence on art and architecture.
