We never stop getting fascinated by Irish tourism. Today we gonna talk about Grianan of Aileach, it is a historic monument in County Donegal, Ireland built on the hill of Grianán and is an Iron Age stone fortress. I think it was restored during 1800s, but it gives a great sense of how the real one was. Get ready for some epic panorama views of Lough Foyle, Lough Swilly and Donegal countryside.
