This large mound of earth just outside the town of Navan has origins steeped in legend. It is said that the mound was originally created as the tomb of a woman named Odhbha, who died of a broken heart when her husband, a Celtic king, abandoned her. Some say that the mound appeared as a result of natural processes.
There are no visible structures on the Motte of Navan today, but a Norman baron, D’Angelo, is said to have erected a motte and bailey here in the 12th century. Motte and bailey represented a traditional Norman style of castle construction during the medieval period.
