This large stone-walled fort, located on a hilltop commanding views over Loughs Foyle and Swilly and counties Donegal, Londonderry and Tyrone, was the royal citadel of the northern Uí Néill from the 5th to the 12th century. It was probably built some time around the birth of Christ. Its builders may have been attracted to this hilltop site by the presence here of a sacred monument - a prehistoric burial mound or tumulus, possibly from the Neolithic period (about 3000 BC).

A lintelled passage through the 4.5m thick wall leads to the interior where the wall rises in three terraces to a height of about 5m; there are also two long passages contained within the thickness of the wall. (These are now closed off to the public).

Substantial restoration work was carried out in 1870. We know little about the three earthen banks which circle the Grianan, but they could be part of an earlier Bronze or Iron Age hillfort. The trackway running through these banks and leading to the fort is believed to be an ancient roadway.
