Back in 1759, Arthur Guinness rode through the gate of an old, dilapidated brewery on Dublin’s James’s Street. He had just signed a lease on the property for 9,000 years at £45 per annum. Today, the site covers 55 acres.

Brewhouse No.4, which opened this week, is only the fourth brewhouse since 1759. At a cost of €169m, it is the largest stout brewery in the world.
