I went to the Guinness Storehouse in Dublin, which has been named the world's leading tourist attraction. Here's why it's a must-visit.

• The Guinness Storehouse was named the world's leading tourist attraction by the World Travel Awards.
• The four-acre brewery site lies in the Southwest of Dublin.
• I visited the brewery to see if the tour lived up to its new title.

For the millions of tourists that descend on Dublin each year, one attraction is often top of their to-do list — the Guinness Storehouse.
