The Royal Canal is a canal originally built for freight and passenger transportation from the River Liffey at Dublin to the River Shannon at Cloondara in County Longford in Ireland. Work commenced in 1790 and lasted 27 years before finally reaching the Shannon in 1817. The canal passes through Maynooth, Enfield and Mullingar and has a spur to Longford. The total length of the main navigation is 145km (90 miles), and the system has 46 locks.There is one main feeder (from Lough Owel), which enters the canal at Mullingar. In 2006 a commemoration marker was erected at Piper's Boreen, Mullingar, to mark the 200 years since the canal reached Mullingar in 1806.
