Located in Brigit’s Garden, the calendar sundial is the biggest calendar sundial in Ireland. 

Constructed in 2006, the sundial tells both the time of day and the month of the year. In order to retrieve this information, it uses very simple but at the same time beautiful techniques. 

A five-foot spike of bog oak is embedded near the centre of a stone circle which casts a shadow across the stone circle. The stone circle has elliptical lines carved in the stone which highlight the month of the year though the use of the shadow. The length of the shadow is then used to determine the different times of the day. 

Although what seems a very simplistic technique, the calendar sundial provides great accuracy in its times and dates using these centuries year old methods.
