Iniscealtra Dial.
The sketch above was made by R.A.S.McAllister in 1916



The twenty four gradations on the sketch of this dial consist of nineteen short incised groves (two of them missing where the dial has been damaged) and five longer radial lines, all set in a circle around a gnomon hole. The horizontal lines equating to Prime - 6am and Vespers – 6pm extend beyond the circle and terminate in crosslets.

This dial was located on Iniscealtra in Lough Derg, Co. Clare. Now lost - whereabouts unknown.

The island of Iniscealtra (also called Holy Island) is reached by boat from Mountshannon 50Km North East of Limerick on the R352 road.
