Poland, the land of Copernicus and Chopin, is an incredibly interesting country with a very rich history. There are many amazing places to see and explore - museums, cathedrals, old city markets, the oldest restaurant in Europe (in Wrocław), the first oil refinery in the world, and so much more. For the off the beaten track enthusiasts there are various unusual places and weird things to see - curious wooden sculptures of Szczepan Mucha, the tallest Pope statue in the world, UFO memorial, dragon bones and what not. The local folklore is fascinating as well, and to travel to the rural destinations within the country is very rewarding.
