Tír Na nÓg is a mythical land in Irish folklore, often described as a paradise where time stands still. It is believed to be a place of eternal youth, beauty, and happiness, free from the troubles of the mortal world. The name translates to "Land of the Young," and it is often associated with the Tuatha Dé Danann, the ancient gods of Ireland. In stories, Tír Na nÓg is typically reached by crossing the sea or through magical means. One of the most famous tales involves Oisín, a warrior who travels to this enchanting realm with Niamh, a beautiful fairy princess. After spending many years there, he returns to find that time has passed differently in the mortal world.
