Sundial (inside red circle) in the ruins of Teampall Ċiaráin on Inishmore, the largest of the Aran Islands off the coast of Galway.

It is believed that St. Ciaráin founded a monastery on this site in the 6th Century when he was studying on Aran with St.Enda.

The current remains of a rectangular medieval stone church may date from the 8th Century







The ancient vertical stone 'noon line' sundial at Teampall Ċiaráin is 1200mm high, 375mm wide, 75mm thick. It has a cross decoration below the vertical noon line which is inscribed within a circle. Nothing remains of the gnomon (the shadow caster) but a 50mm diameter hole where a wood or metal horizontal gnomon would have been fitted. Other timelines may have been painted on the dial face.

One of the Aran Islands, Inis Mór (the big island), is one of the most popular tourist destinations in Ireland. It is well known internationally with over 50 different monuments of Christian, pre Christian and Celtic mythological heritage. Ferries to the Aran Islands are available from Rossaveal (leaving Galway city) all year and from Doolin (Cliffs of Moher) from April to October.
