Shane's Castle is a ruined castle near Antrim in County Antrim, Northern Ireland, which was mostly destroyed in 1816 by fire. The castle is situated on the north-east shores of Lough Neagh, 2.7 miles from Randalstown. Built in 1345 by a member of the Clandeboy O'Neill dynasty, it was originally known as Edenduffcarrick, meaning "brow of black rock" (from the Irish éadán dúcharraige).[1][2] It owes its present name to Shane McBrian McPhelim O'Neill, who ruled Lower Clandeboy between 1595 and 1617.[2]
