A museum for question-mind minds, it is also for those who like to tinker and learn how things work, or rather how things might work in the future. The German Museum of Technology in Berlin has a wide collection of planes, boats, trains and cameras, which show the development of amazing German engineering over the decades, for which the country is famous. There is so much to see here from old steam trains to railcars and an entire section on aviation, it would be wise to book a full day to explore all that this museum has to offer.
