The Donaghmore Round Tower is a well preserved 10th century construction situated just northeast of Navan in County Meath. The tower is found on the site of a religious settlement thought to have been established in the 5th century by St Patrick and left under the direction of his disciple, Cassan (Cassanus).
At the site, visitors can view the remains of a church and the round tower, which has interesting carvings and sculptures.
