Tír na nÓg (teer na nogue) was the mythical land of everlasting youth, where the Fountain of Youth would ensure that whoever drank from it would become young again, and never age. According to Irish legend, Tír na nÓg lay off the west coast of Ireland. The Irish heroes of legend travelled to Tír na nÓg to drink the water from the Fountain of Youth. Also, the Tuatha De Danann travelled to Tír na nÓg when they were defeated and driven out of Ireland.
