In the town of Casar de Caceres, located 10 kilometres from the capital of Caceres, the architect Justo Garcia Rubio planned his most audacious work: a terminal for long-distance buses featuring complex engineering and a superbly slender design.

The most characteristic element is the curved white concrete ribbon which folds in on itself and serves as a roof and as a depot for travellers and vehicles. A laminar structure resembling a sculpture, whose shape is not only designed to be aesthetically pleasing, but also functional: it expels the contamination from the buses' exhaust pipes and diverts it away from the schools flanking the station.

The result is strongly reminiscent of the soft architecture pioneered by other architects such as Oscar Niemeyer and Felix Candela.
