There are so many projects in progress in Madrid that it seems the hole city is under construction."The city will be marvellous when it will be finished", Danny DeVito said when he visited Madrid time ago.
We have the famous CTBA where there will be four skyscrapers of 200-250 metres high (the tallest buildings of Spain) and a new exhibition centre that seems a huge manchego cheese
Cuatro Torres Business Arena Madrid International Convention Centre Another project is "La Caja Mágica" (which will be part of the Olympic Games if Madrid achieves to host them) in Usera district.
La Caja Mágica The old slaughterhouse is being refurbished to celebrate cultural activities.
Matadero de Madrid (spanish) There are two more projects that haven't still begun: the refurbishment of the Prado-Recoletos area and the construction of a huge obelisk in the middle of Plaza Castilla, although I don't know if the last one is going to be carried out.
And I'm sure I've forgotten more...
