Podborka, Russia appears to be unusual

Lots of the Flickr photos tagged Podborka are interesting. What kind of city does this? And when have you seen this or this?
And are there Siberian tigers in city limits? The animals certainly seem friendly.

Of that group of photographers, I judge thepuppetrmaster currently the best.

Podborka is near to Arkhangelsk.
