The renovation of Cibeles Palace
In my opinion, it is the loveliest building in Madrid. It is worth going through all the floors and spots, it is a magnificent building.
Inside, on each floor, there are many surprises. If you start with floor 0, where there is a space dedicated to reading or relaxing, right next to desks with tactile screens to play and learn with information and pictures of "before" and "after" the renovation Palace. Further the old postal service stands (the Spanish Correos), exactly as it was at the time, which gives way to the glamor of other times.
We can go up the lift or the fabulous stairs to other floors (there are eight of them, including the tower and two lower floors). These stairs are decorated with spectacular glazed tile. On each floor, you discover something new, the glass floor, the very worked roofs, the painted glass and the huge exterior glass dome.
