The Round Tower
Round Tower
Immediately adjoining the cathedral to the southwest stands the Round Tower, built about 1000 A.D. It is 86 ft.(26.21 m) high, has at the base a circumference of 50 ft.(15.3 m) and a diameter of 16 ft.(4.9 m), and is capped with a hexagonal spire of 18 ft.(5.5 m), added in the 14th century. This type of structure is somewhat common in Ireland, but the only Scottish examples are those at Brechin and Abernethy in Perthshire.
The quality of the masonry is superior to all but a very few of the Irish examples. The narrow single doorway, raised some feet above ground level in a manner common in these buildings, is also exceptionally fine. The door-surround is enriched with two bands of pellets, and the monolithic arch has a well-preserved representation of the Crucifixion. The slightly splayed sides of the doorway (also monolithic) have relief sculptures of ecclesiastics, one of them holding a crosier, the other a Tau-shaped staff.
