If you want to have an idea of Milan, its shape and surroundings and also of the new areas that are being built, then I suggest to see the city from above.
The best place to do it is at the tower of the so called Palazzo Lombardia, one of the first new buildings created in view of the EXPO. It is the seat of the government of Lombardia region and it is made of steel and glass, with round shapes and sharp corners that give it a futuristic look.
The entrance is at the corner with via Restelli, just before the Isola neighborhood. Once in the hall don’t forget to look at the columns, they are all different from one another since each one was decorated by a different contemporary artist. Which one is your favorite?
You then take an elevator that gets to the 39th floor in a few seconds and from there the view is amazing. The Dom is just 1.7 km away, the Unicredit skyscraper is just in front of you, and what about the so-called bosco verticale (vertical wood)? It is a building with deep terraces where big trees have been planted so as to create a garden/wood that develops towards the sky. Despite the many awards, Milanese people do not seem to appreciate it (or maybe it is just envy? It seems that the apartments cost more than € 12.000 per sqm).
