The Long Night of Museums, first organised here in Berlin in 1997 and now copied worldwide, is this year planned for Saturday, 31th August, when from 18:00 until 02:00 (although times do vary for some attractions) just about every museum across Berlin (75 in all) will open its doors, with over 800 special events, exhibitions, tours, children's activities and concerts. You can walk between museums or use free shuttle buses. Tickets cost €18 (€12 concessions, free for kids under 12) and include access to all museums, the shuttle buses, public transport (from 15:00-05:00) . For more information and the free smartphone app see the English-language site www.lange-nacht-der-museen.de/en. Tickets can be purchased online, from BVG and S-Bahn ticket machines, tourist information, and participating museums. The hub of the Long Night of Museums is the Kulturforum at Potsdamer Platz.
