The Curragh is a flat open plain of almost 2000ha of common land in County Kildare, Ireland, between Newbridge and Kildare. This area is well known for Irish horse breeding and training. The Irish National Stud is located on the edge of Kildare town, beside the famous Japanese Gardens. Also located here is Pollardstown Fen, the largest fen in Ireland. This area is of particular interest to botanists and ecologists because of the numerous bird species that nest and visit there. There are also many rare plants that grow there.It is composed of a sandy soil formed after an esker deposited a sand load and as a result it has excellent drainage characteristics. This makes it a popular location for training racehorses.HistoryUsed as a meeting site during Pre-Christian societies, the Curragh is shrouded in a mist of mythology. The hill north of the Curragh is called the Hill of Allen (Almhain) and is the meeting place of the mythical Fianna. Legend has it that in about 480 AD, when St Brigid became intent on founding a monastery in Kildare town, she asked the High King of Leinster for the land on which to build it. When he granted her as much land as her cloak would cover, she then placed her cloak on the ground to cover the entire Curragh plain.
