Irish round towers are early medieval stone towers of a type found mainly in Ireland, with two in Scotland and one on the Isle of Man. As their name Cloigtheach indicates, they were originally bell towers, though they may have been later used for additional purposes.
The round tower at Glendalough, Ireland, is approximately thirty metres tall.
The Round Tower at Kinneigh has a unique hexagonal base.

Brechin is a town and former royal burgh in Angus, Scotland. Traditionally Brechin was described as a city because of its cathedral and its status as the seat of a pre-Reformation Roman Catholic diocese, but that status has not been officially recognised in the modern era.
