discovering backyards in the old town
The old town of Lublin has preserved much of iths original character, looking even a bit run down in comparison to the renovated facades in Krakow or other more touristic cities. I personally like just to walk a bit through narrow lanes and backyards where you still can fond little shops and workshops.
