This restored 13th century fortification was originally built by Meiler de Bermingham and is located within the heritage town of Athenry.
Richard de Burgo granted a charter to Meiler de Bermingham in 1235 and shortly afterwards de Bermingham started building his castle at Athenry.
Probably completed by 1250, it consists of a three-storey tower surrounded by the remains of a strong outer wall and is entered at first floor level through an unusually decorated doorway.
Recently re-roofed, the interior now contains an audio-visual room and exhibition.
