Wish the first picture was larger, it looks like an old building. Any details? Really like the fourth shot, its busy but in this picture it works, very nice,
Cruzin ... this what you called "old building" is a simple tenement-house. It was built in early 1900s.
Here in my city there are many buildings like that. The city became Polish in 1945. Before this date it was German for centuries and... Napoleon Bonaparte had his base here during the war with Russia
