Name Toberbarry County Roscommon Nearest Town Elphin Access Road N5 About Toberbarry, County Roscommon is a series of mounds and fairy forts located about ten kilometres north of the village of Tarmonbarry in east County Roscommon.

There is little evidence provided as to their history, but they are presumed to be of the megalithic era and may be connected to the Rathbeg and Cruachan, capital of the Kingdom of Connacht constructed by Queen Medb and her husband Ailill which spread over a wide area believed to go as far east as Longford.

This would give some credence to the theory.
