Milan, Italy

While walking in the hospital's lanes I can reach a big room with enormous windows giving me a look to the outside world. Fortunately just on the other side of the road there's a small park giving me a bit of fresh air and a wellness sensation, like if I can smell the clean air out there.On the background there's the city Skyline forming and evolving, with five of the most iconic buildings of the city.

Can you name them?
