The Grand Canal (Irish: An Chanáil Mhór) is the southernmost of a pair of canals that connect Dublin, in the east of Ireland, with the River Shannon in the west, via Tullamore and a number of other villages and towns, the two canals nearly encircling Dublin's inner city. Its sister canal on the Northside of Dublin is the Royal Canal. The last working cargo barge passed through the Grand Canal in 1960. Source: Wikipedia (en)
