History
Main article: History of Roads in Ireland
There have been routes and trackways in Ireland connecting settlements and facilitating trade since ancient times. Ireland was never part of the Roman Empire and, therefore, Roman roads were not built in Ireland. However, an Iron Age road with a stone surface has been excavated in Munster and togher ( Irish: tóchar) roads, a type of causeway built through bogs, were found in many areas of the country. According to an entry in the Annals of the Four Masters for AD 123, there were five principal highways ( Irish: slighe) leading to Tara ( Irish: Teamhair) in Early Medieval Ireland .
