Holy Wells
There are hilltop wells like the one at Slievesnacht (Sliabh Sneachta - Mountain of Snow.) This well is called Tobar na Suil (Well of the Eyes) and there are stations along the hillside on the climb up to it. It is believed to have been blessed by Saint Patrick. Nearby is the trignometrical station which was the first point in the Ordnance Survery of Ireland in 1835.
There are wells along the shore edge like the one at Binion which is covered by the tide and like Saint Columba's well at Moville and others already mentioned. Many of the wells are underneath a thorn tree, like Saint Patrick's well at Glentogher and Saint Ultan's well. Saint Patrick's well at Three Trees near Iskaheen is under a tree also. There is a cealdragh near the well at Three Trees, near Eithne's well and I was told that there is one near the well at Glentochar also.
Some wells, like the one at Slavery, have bullaun stones - stones with one or two round hollows - beside them. These were usually called wart wells and it was believed that the water in the hollow had healing properties for the treatment of warts. Some other wells were considered to have special properties in the treatment of headaches, toothache and other ailments.



Saint Patrick's Well
The nearest holy well dedicated to Saint Patrick is at, Grianan Aileach. The cashel is a very historic spot, and so is the little well at its southern side. Here a chief of Inishowen was baptised by Saint Patrick. Patrick had come to Inishowen after visiting Tir Chonaill, the western part of Donegal which is separated from Inishowen by Lough Swilly. He went to the hill fort at Aileach to see Eoghan, a brother of Connall's chief of this territory, Inish Eoghain (Eoghan's Island) Eoghan wished to become a Christian and so Patrick baptised him at the well which lays a little distance downhill form the fort. The chief's family and servants were also converted and baptised.

There are several places connected with Patrick in Inishowen - Carndonagh where he founded a church, Moville where another was founded by him, Iskaheen where Prince Eoghan who was baptised by him is buried, a lake in the hills at Malin Head, a holy well at Three Trees near Iskaheen and a holy well at Magh Tochar near Carndonagh.
