The Knockans is an Iron Age linear earthwork located in south-west Ireland, believed to be the site of the ancient Tailteann Games.
One of a number of Irish Iron Age linear earthworks, the Knockans is a double-banked monument partly destroyed by bulldozer in May 1997, which saw the northern bank totally destroyed and other material damage done.
