St. Patrick's College

What was once a center for the training of Catholic priests is now one of Ireland's most important lay universities. The visitor center chronicles the college's history and that of the Catholic Church in Ireland. Stroll through the university gardens—the Path of Saints or the Path of Sinners. At the entrance to St. Patrick's College are the ruins of Maynooth Castle, the ancient seat of the Fitzgerald family. The Fitzgeralds' fortunes changed for the worse when they led the ill-fated rebellion of 1536. The castle keep, which dates from the 13th century, and the great hall are still in decent condition.
