Kaliningrad is an interesting place. It's an exclave of Russia, located on the Baltic Sea, separated from the rest of the country by Lithuania and Poland. It's a fascinating mix of old and new, with a historic city center that's been largely preserved, and modern high-rise buildings and malls. There's also a large Russian military presence in the city, which gives it a unique feel. It's a great place to explore on foot, and there are some interesting museums and other attractions worth checking out.
