Aircraft, vehicles, cutting-edge technology, historic machinery, and even a mine fill a monumental building on an island in the Isar River, which comprises one of the best science and technology museums in the world. The collection is spread out over 47,000 square meters, six floors of exhibits, and about 50 exhibition areas. The Centre for New Technologies includes interactive exhibitions, such as nanotechnology, biotechnology, and robotics. It could change the way you think about science forever. Children have their own area, the Kinderreich, where they can learn about modern technology and science through numerous interactive displays (parents must accompany their children). One of the most technically advanced planetariums in Europe has four shows daily. The Internet café on the third floor is open daily 9–3, other cafés until 4. To arrange for a two-hour tour in English, call at least six weeks in advance. The Verkehrszentrum (Center for Transportation), on the former trade fair grounds at the Theresienhöhe, has been completely renovated and houses an amazing collection of the museum's transportation exhibits.
