Hash, Marihuana & Hemp Museum

Museum in La Rambla & Barri Gòtic

The world's largest museum dedicated to all things cannabis-related opened to much fanfare in 2012 (even Virgin founder Richard Branson was at the opening). Set in the beautifully restored 16th-century Palau Mornau, exhibitions delve into the role the plant has played over the years, with 19th-century medicinal cannabis bottles, pulp film posters and consumer products made from hemp among the displays.
