History and geology blend at Dunmore Cave to give an interesting and unique situation. Dunmore Cave contains a quarter of a mile of passages and its deepest point is 150 feet below the surface. The Cave was known as one of the darkest places in Ireland. In 928 A.D. the cave was plundered by Godfry and the Vikings of Dublin and more than 1,000 people were slain. In 1999, a hoard of silver and bronze items was discovered in the cave. Archaelogists date the hoard to 970 A.D. The cave is just over a 10 minute drive from Kilkenny city.

Exhibitions and displays in the Visitor Centre. The caves are inaccessible for wheelchair users. The Interactive Virtual Museum includes many treasures found in the Cave including one of the most significant Viking finds in the country.
