Almost midway between Athlone and Mullingar on the R390 is Uisneach, the 'centre' of Ireland. Well, not really – that's a few kilometres to the west. But it is a site with great ancient significance. Ancient constructions found so far include earthworks that may have been a royal palace, a possible fort, some holy wells and more. On tours (the only way to visit), you'll get a detailed overview of the ancient sites plus the associated lore. The 2-sq-km site is mostly privately owned.
