The Tun Room is named after the large fermenting vessels used during the brewing process of GUINNESS® beer. This room is located in a quiet corner on the fourth floor. With the unusual feature of a large tunnel connecting the GUINNESS STOREHOUSE® with the Robert Street Malt-store and four large arched windows, the room is airy and bright - creating a distinctively fresh atmosphere. The fantastic views over the Brewery and city provide the perfect backdrop for either private dining occasions or meetings and presentations.
