Guiness Brewery Front Gate

St. James's Gate Brewery (Irish: Grúdlann Gheata Naomh Séamuis) is a brewery founded in 1759 in Dublin, Ireland, by Arthur Guinness. The company is now a part of Diageo, a company formed from the merger of Guinness and Grand Metropolitan in 1997.     The main product of the brewery is Guinness Draught.   Originally leased in 1759 to Arthur Guinness at £45 per year for 9,000 years, St. James's Gate has been the home of Guinness ever since. It became the largest brewery in Ireland in 1838, and was the largest in the world in 1914, covering 64 acres.
