From a recent visit to an Grianán Ailigh (Grianán of Aileach) - a hillfort in
#Donegal, probably built in the 6th or 7th century, destroyed by the King of Munster at the start of the 12th century, and rebuilt from the ruins in the 19th century (with further restoration work in this century). It's a strange patchwork of eras, but it really is a magical place.
