 There is no precise definition of the Grand Canal Dock area but it is generally understood to be bounded by the Liffey to the north, South Lotts Road to the east (or Barrow Street if separating South Lotts as its own area), Grand Canal Street to the south and Macken Street to the west (although some maps show the area including as far west as the corner of Leeson Street and Fitzwilliam Place).Grand Canal Dock contains Grand Canal Dock railway station (also known as Barrow Street Station), the national Waterways Ireland Visitor Centre, the site of the planned U2 Tower, and a number of other notable buildings.Grand Canal Dock railway station, accessed from Barrow Street, opened in 2001 (although the line has been in use since 1834).
