The tower is 74 feet high and was used both as a watch tower and as a shelter for the monks from the local monastery.
This ancient slim Irish Celtic round tower (one of only two to survive in Scotland - the other is in Brechin) was probably built towards the end of the 11th century. It was in this Perthshire town when King Malcolm III may have knelt in feudal submission to William the Conqueror in 1072, only six years after the Norman lord had conquered England.
