The name Shandon comes from the Irish, "Sean Dún", meaning "old fort". A medieval church dedicated to St. Mary existed close to the site of this fort, and is mentioned in the decretals of Pope Innocent III in 1199 as "St. Mary on the Mountain". This church stood until the Williamite wars when it was destroyed during the siege of Cork (1690). In 1693 this was replaced by a church, also dedicated to St. Mary, and was located at the bottom of Mallow Lane, modern day Shandon Street. Due to population growth, it was decided to build anew on this ancient site and so in 1722 the present Church of St. Anne, Shandon was constructed.
