Castletroy (Irish: Caladh an Treoigh) is a suburb of Limerick, Ireland and is the largest suburb in Munster. Historically, the district was entirely separate to Limerick, and consisted of little development aside from the villages of Annacotty and Monaleen. With the creation of the University of Limerick, as well as the growth of Limerick city itself, this began to change. Castletroy is one of the fastest-growing residential areas in Ireland and has now engulfed the old villages of Annacotty and Monaleen (Móin a lín - field of flax). * Castletroy's Jewish graveyard *
