Boyne Navigation
 The Boyne Navigation (Irish: Loingseoireachta na Bóinne) is a series of canals running 31 km (19 mi) roughly parallel to the River Boyne from Oldbridge to Navan in County Meath in Ireland. The navigation was once used by horse-drawn boats travelling between Navan Slane and the port of Drogheda; however is now derelict.
