County Louth (An Lú in Irish) is a county on the east coast of Ireland. While a popular theory is that the Irish version, An Lú, means “the least”; Louth having been the smallest of the original counties, the county actually takes its name from the village of Louth (Lughbhadh in Irish, referring to the Celtic god Lugh. The county town of Louth is Dundalk. The majority of the county’s population live either in Dundalk or in the town of Drogheda.
