Ireland’s smallest county is packed with history, from the medieval town of Carlingford to the mysterious Proleek Dolmen, an ancient portal tomb that has stood for thousands of years. Louth is also home to Drogheda, a town with historic sites like St. Oliver Plunkett’s preserved head—an unusual but fascinating relic. Every August, the county plays host to the Fleadh Cheoil na hÉireann, Ireland’s biggest traditional music festival, attracting musicians and fans from all over the world.
