Tobernalt is a holy well in north County Sligo, Ireland near the southwest corner of Lough Gill. It is an ancient natural spring dating back to the 5th century as a pagan meeting place and later a Penal Law mass site.[1]
it is maintained by St John's Parish, Carraroe, Sligo.[2] Masses are conducted at the site. The devoted from surrounding counties and elsewhere make pilgrimages to the site on Garland Sunday when a day-long schedule of devotions is held.
It is associated with St. Patrick whose fingerprints are said to be in the stones of one of the altars.
