Fairy fort / stone ringfort in Carrownalassan

Fairy fort / stone ringfort in Carrownalassan is a fairy fort or stone ringfort in Carrownalassan, County Roscommon, Ireland. It occupies a gentle south-facing slope with outcropping rock, forming a subcircular grass-covered area twenty-six point seven metres north-south and twenty-three metres east-west. A grass-covered stone spread two to two point three metres wide and ten to thirty centimetres high marks the SSW-N-SE boundary, with intermittently visible facing-stones at the north reaching one point two metres in original width. No identifiable original entrance remains, and Rath RO028-215 stands approximately one hundred and fifty metres to the north-northeast.
