The last of my Celtic Crosses of Iona’s Abbey is St John’s Cross, which is a replica, the original is in the abbey museum. It was once one of the widest crosses known in the British Isles. The cross was carved over 1200 years ago and the carvers wanted to make something large and wonderful, but they over did it and it kept toppling over. In 1927 the pieces were stuck together, but only lasted until 1957, when the remains were removed to the museum. A replica was made in 1970 and is made of concrete.
