A 140m tall building with its own postal code and a famous sinuous facade designed by Oscar Niemeyer. There are more than a thousand flats in it and it is home to 5,000 residents. Therefore, the interior is not accessible to the public but even from the outside, this gem of architecture is worth seeing.
