The Grianán of Aileach

GriananOutsideDONEGAL, IRELAND — In the northeastern part of the county, about 7 km west of Derry in Northern Ireland, is Greenan Mountain. On its very top is a spectacular ringfort called The Grianán of Aileach (“the Solarium of Aileach”, shown above). From it are spectacular views of the countryside 360° around. It is a majestic and yet rather lonely place, maybe because my new friend Andy Quinn and I were the only ones there. It was probably built in some form around the beginning of the common era and no doubt occupied by many successive groups. There is a burial mound on the site (a tumulus) that may date back to 3000 BCE. The local story is that it was originally a place to honor the sun (which I would not have minded seeing today).

The fort’s most prominent days were when it was the royal citadel of the northern Ui Neill sept of Aileach from the 5th to the 12th century. The stone portion of the fort was destroyed in 1101 by Murtogh O’Brien, King of Munster. His soldiers were ordered to take the fort apart and scatter its stones widely. In 1870 it was substantially restored to its present state.

The Grianán of Aileach was an excellent location to visit and have a look at the countryside of eastern County Donegal. The rocks exposed here are among the oldest in Ireland (Late Proterozoic to Early Cambrian).

An Irish myth says that The Grianán of Aileach was built by King Daghda of Tuatha de Danann, and that the grave of his son lies beneath the fortress forever guarding it. In any case, we were suitably respectful of this ancient site.
