Sáenz de Oíza's organic 1960s concrete tower in Prosperidad — a Brutalist-meets-futurist landmark of curving balconies and tubular cores that, despite its name ('White Towers'), is a single rugged structure of raw concrete. Conceived as a vertical garden city, it's one of the most celebrated works of 20th-century Spanish architecture, beloved by enthusiasts for its sculptural, almost biological forms. It remains a private residential building. For architecture travelers, the exterior is the reward — an audacious, organic high-rise unlike anything else in Madrid, and a key monument of postwar Spanish modernism well worth the trip out from the center.

The bare board-marked concrete — it was never white, and the name honours Le Corbusier's purism rather than any cladding. From the street, read the stacked cylindrical balcony drums pinwheeling around the shaft: the architect wanted a tree, with lifts as trunk and terraces grouped like leaves. There are no columns at all.
Low raking light; flat midday sun flattens the balcony drums. No crowds and no hours — it is a street-corner view at Avenida de América 37, Metro Avenida de América or Cartagena.
Confirmed closed to the public: a private residential and office block with no visitor operation. The twenty-second-floor restaurant, historically the only enterable space, is being converted into flats. Do not attempt the lobby — this is an exterior view only.
