This is a county steeped in myth, legend and history, going back to the pre-historical days of the Táin Bó Cúailnge (Cooley Cattle Raid, see Cú Chulainn). Later it saw the influence of the Vikings as seen in the name of Carlingford Lough. There are a number of historic sites in the county, including religious sites at Monasterboice and Mellifont Abbey. In the early fourteenth century the Scottish army of Edward Bruce (brother of Robert of Bannockburn fame) was defeated in the Battle of Faughart near Dundalk, Edward losing not only his claim to the High Kingship Of Ireland, but also his life. The sixteenth and seventeenth centuries featured many skirmishes and battles involving Irish and English forces. Oliver Cromwell attacked Drogheda in 1649 slaughtering the Royalist garrison and hundreds of the town's citizens (Siege of Drogheda). Towards the end of the same century the armies of the warring Kings, James and William, faced off in South Louth during the build-up to the Battle of the Boyne - the battle takes its name from the river Boyne which reaches the sea at Drogheda.
The M1 from Dublin to Belfast passes through the county.
The towns of Dunalk and Drogheda have stations on the Dublin to Belfast railway.
County Louth is beside the sea. Getting there by boat shouldn't be too dificult.
