About a mile north-east of Navan, County Meath lie the remains of the once-important monastic settlement of Donaghmore. A witness to Christmas for more than 1,500 years, it was supposedly founded by St Patrick; he later passed on responsibility for the site to his disciple St Cassanus. All that remains of the monastery is this round tower, believed to date from the 12th century. Next to it are the ruins of a former parish church probably early 16th century, with a double bell cote on the west gable.
