The Guinness Storehouse, also known as Guinness Hop Store is located at St. James's Gate Brewery in Dublin, Republic of Ireland. Since opening in November 2000, it has attracted over 4 million visitors. The Storehouse is laid out over seven floors surrounding a glass atrium in the shape of a pint of Guinness. The ground floor introduces the beer's four ingredients, water, barley, hops and yeast, as well as the brewery's founder, Arthur Guinness. Other floors feature the history of Guinness advertising and an interactive exhibit that encourages responsible drinking. In 2006, a new wing opened incorporating a live installation of the present day brewing process. The seventh floor houses the Gravity Bar where visitors may claim a complimentary pint of Guinness and enjoy the 360° views over Dublin City.
