Dun Ruadh, meaning "Red Fort", is situated near the site of the former Crouck School, about 7km north of An Creagán.
This is a large circular burial cairn surrounded by a ditch and bank. The cairn is made of a ring of stones with dry walling between them and inside there are 13 cists or burials. This cairn was built about 4000 years ago in the Bronze Age.
Open all year, always ask permission from the owner of the farm located at the end of the lane leading from Crouk old school.
