National Technical Museum
For those who have an interest in the history of technology, a visit to the National Technical Museum is a must. Being the largest institution of its kind in the Czech Republic, the museum has a huge exhibition featuring a wide range of technologies, from cars and aircrafts to bicycles and mining equipment, astronomical instruments, print history artifacts, different styles of architecture designs - and even early home appliances such as vacuum cleaners, washing machines and refrigerators. On top of that, there's a nice canteen with beer on tap, cakes and other refreshments, so if it’s a rainy day, this is definitely worth checking out. Who knows, you might even learn something new!
