Hash Marihuana & Hemp Museum Barcelona, 35 Carrer Ample, Barcelona, Spain

Palau Mornau was built in the 16th century as a palace for the noble Santcliment family. These days the elegant Modernist/Renaissance building in the Gothic Quarter of Barcelona serves a different purpose. Dutch entrepreneur Ben Dronkers started the Hash Marijuana and Hemp Museum, renovating the building to its former glory and displaying some 8,000 items relating to cannabis throughout mankind’s history. The topics cover both recreational medical usage and also industrial applications.
