Built in 1980 by Francisco González Valdés and destined to be the Head Offices of the Spanish Medical Council. But the Medical Council couldn't adapt to the circular design and so they declined to use the building. Instead it was occupied by the court / tribunal dealing with constitutional affairs and disputes, and therefore an important institution in Spanish politics. This building is often seen on the news. Unlike most such places, this is some way away from the political centre, being on the edge of the vast Universitaria complex.
