The Carntogher area is rich in archaeological heritage. The area boasts many forts and raths, a swaet house, Tirnony Dolmen, and the iron age and bronze ages carns on top of Carntogher itself.
Much of the archaeology of the area still remains to be discovered and discussed.
ENVISION had LiDAR analysis of an area 9-square kilometres commissioned for archaeological analysis around Tirnony Dolmen and Tullyheran Fort. This data is available for use by researchers of all levels.
