What Travellers Say
Reviews Summary
Visitors find Castletown Motte and Mill a fascinating site, rich in both Norman history and Irish legend, particularly Cú Chulainn's story. While praised for its unique character and well-kept grounds, the lack of parking and challenging access due to uneven terrain and steps are recurring drawbacks.
"Cú Chulainn’s Castle (Dún Dealgan Motte & Bailey)
A small but fascinating site overlooking the fields outside Dundalk, tied to Ireland’s greatest hero, Cú Chulainn.
Practical tip: there’s no parking, so you’ll need to carefully pull in at the roadside. The entrance is by climbing the stone steps built into the wall — not through the farm gate that says No Trespassing.
The ruin itself is actually a Norman motte-and-bailey castle, first built around the 12th century, and later reused in the 18th century when a tower house known as “Byrne’s Folly” was built on the mound. Over time, it became deeply connected with the legends of Cú Chulainn, who was said to have made his home here.
Local folklore adds more colour: in the field beside the mound lies a large stone, believed to have been thrown there by Cú Chulainn in a show of superhuman strength. Stories say the hero could hurl massive boulders as casually as a child throws a ball, and this one is pointed out as proof.
Standing here, you get both sides of the story — the solid earthwork of the Normans, and the epic myth of Ireland’s warrior champion. Quiet, raw, and steeped in layers of history and legend, it’s a rewarding stop for anyone exploring Louth."

"A very nice old castle ruin in lovely well kept grounds. It has no real parking but you will find parking in the local estates near by, its easy to miss the entrance as it looks like an entrance to a field. But when you do get up to the castle it is lovely and unique, I loved it you will too, enjoy"

"Lovely old and small round castle ruin situated on top of a hill. But if you're not good on foot it's difficult to reach. Definitely not recommended if disabled or difficulties walking. No parking, had to park nearby in an estate"
