Dublin Port (Irish: Calafort Átha Cliath) is a seaport in Dublin, Ireland. It has both historical and contemporary economic importance. Approximatively two-thirds of the Republic of Ireland's port traffic goes via Dublin Port. Recently, the port and its land, mostly at the eastern end of Dublin's Northside, were valued at €25 billion – €30 billion.
The modern Dublin Port is located either side of the River Liffey, out to its mouth. On the north side of the river, the main part (205 hectares or 510 acres) of the port lies at the end of East Wall and North Wall, from Alexandra Quay. The element of the port on the south side of the river is much smaller (51 hectares or 130 acres) and lies at the beginning of the Poolbeg peninsula.
The main activity of the port, as per the statistic above, is freight handling, with a wide range of vessels, from large container carriers to small diesel lighters, visiting daily.
Roll-on/roll-off ferry services run regularly across the Irish Sea to Holyhead in Wales, Liverpool in England and in the summer months and at Christmas to Douglas, Isle of Man. The largest car ferry in the world, the Irish Ferries ship MV Ulysses which can carry up to 2000 passengers, runs on the Holyhead route.
Dublin Port is also a docking area for cruise liners.
The port is operated by the semi-state Dublin Port Company, incorporated on 28 February 1997 (formerly the Dublin Port and Docks Board and successor to the Ballast Board founded in 1707), whose headquarters are located just beyond the main port entrance north of the Liffey. According to the DPC, the port handled 23.5 million tonnes of cargo in 2003, as well as 1,426,000 passengers. That year 7,917 ships docked in the port, including 54 cruise liners carrying 54,000 visitors.
