In which Irish county is the famous racecourse 'The Curragh'?

The Curragh Racecourse, usually referred to as simply 'The Curragh', is Ireland's most important thoroughbred racecourse. It is situated on the Curragh plain in County Kildare, between the towns of Newbridge and Kildare.

The name "Curragh" comes from the Irish (Gaeilge) word Cuirreach, meaning "place of the running horse". The first recorded race on the plain took place in 1727, but it was used for races before then. The first Derby was held in 1866, and in 1868 the Curragh was officially declared a horse racing and training facility by act of parliament.

The course is right-handed, about two miles long and horseshoe-shaped. Races up to one mile are run on a straight course. Additionally there are several training facilities on the site. The Curragh offers the highest purses and highest quality level of flat racing in Ireland. In 2007, ten of Ireland's twelve Group One races were held at the track.
