In Kończyce Wielkie, a nice village in the commune of Hażlach in Cieszyn Silesia, there are a few interesting historic buildings and impressive monuments of nature. The latter are oaks that can be a subject of envy even on part of national parks. The tree called "Mieszko" (from the name of the duke, the founder of the Cieszyn Piast dynasty) is the oldest one in Silesia. It is more than 750 years old!
