Thanks for this virtual architectural tour of Poland. I love seeing the variety (even the communist block houses, though they ARE ugly!).
Poles really seem to have a thing for fences, don't they? There is a Polish family who moved to the town that I work in. I know of them because their children were in my school. Everyday on my way to work I drive by their house and chuckle. It is a neat, trim, clean, small ranch house (what we call a house built all on one level with no upstairs). The Polish gentleman built a fence in front of it and on either side of the driveway he constructed two columns out of brick with fancy terra cotta planters on top. They are so ornate for such a tiny house, but seeing your pictures, I see how very Polish the design is and I love it!
There are a few of them in my area. In 1970s Santa Claus gave me a book with poems about Krakow by a minor Polish modern poet, Tadeusz Śliwiak. One poem was about blocks that were being built at the time. Śliwiak described their great qualities, one of them was an open-top terrace on the roof where children could have fun.
Unfortunately, it was typical communist propaganda. Endless promises, advocating patience till one day we live in Paradise.
There are terraces on the rooftoop indeed but I am afraid they have never been used by children to have fun.
A set of photos from one drive through Krakow. You can see modern architecture of 1990s and 2000s, as well as 19 century tenement houses and blocks or private houses from communist times. Plus a few pre-war wooden houses ( which war - 1 or 2?) and one medieval castle. ;D ;D ;D
