Splendid walk through wonderful park

I had the opportunity to walk through a beautiful park in wonderful city of Cracow, Poland.
The park surrounds the old city, it's green oasis in a heart of city with population around 1 mln inhabitants. Cracow has beautiful architecture, old buildings from various periods, some as old as 1000 years. A lot of green areas, old trees in addition to that, makes it a real gem, among the European cities. I also want to mention that it's very clean. Pure pleasure to walk.
