Dún Dealgan Motte, Medieval motte-and-bailey castle in Dundalk, Ireland
The fortress stands on a ridge overlooking the Castletown River, featuring a raised earthwork mound that supported wooden defensive structures during medieval times.
Built in the late 12th century by Bertram III de Verdun, the castle served as a stronghold for Hugh de Lacy until King John's forces prompted its abandonment in 1210.
Local tales identify the site as the birthplace of Cu Chulainn, with a standing stone near the castle marking the legendary Irish warrior's reported burial location.
Visitors need to walk over a stone fence and climb stone steps for approximately 5-10 minutes to reach the castle ruins at the top of the mound.
A 17-meter Z-shaped souterrain tunnel, constructed during the Gaelic period, runs through the hill beneath the castle structure.
