This majestic stone castle was founded in the early thirteenth century. It became the seat of power for the FitzGeralds, the earls of Kildare, as they emerged as one of the most powerful families in Ireland. Garret Mór, known as the Great Earl of Kildare, governed Ireland in the name of the king from 1487 to 1513.
Maynooth Castle was one of the largest and richest Geraldine dwellings. The original keep, begun around 1200, was one of the largest of its kind in Ireland. Inside, the great hall was a nerve centre of political power and culture.
Only 30 kilometres from Dublin, Maynooth Castle occupies a deceptively secluded spot in the centre of the town, with well-kept grounds and plenty of greenery. There is a captivating exhibition in the keep on the history of the castle and the family.
