Killone Abbey (Irish: Mainistir Chill Eoin[1]) is a former nunnery located on the grounds of Newhall Estate in County Clare, Ireland.

A narrow stone stairway, situated between the altar and the east window, leads to a ledge atop the south wall of the church, offering views of the surrounding grounds.

[4] The site is widely regarded for its serene atmosphere, spiritual significance, and natural beauty, making it a cherished landmark in the local area.

[7] Also located on the grounds of Newhall Estate is Holy Well of Saint John the Baptist, known as Tobar Eoin in Irish, which has long been a site of religious significance.

[11] Lord Walter Fitzgerald (the fourth son of Charles, Duke of Leinster) visited the site in 1899 and documented its history in Inscriptions at St. John’s Well, Killone Abbey, County Clare for the Royal Society of Antiquaries of Ireland.
