Calle de Emilio Campión
It bears the surname of the Navarrese Campión, in a colony where the streets take the names of rivers, several from the Basque Country and Navarre, though no record survives of who this Emilio Campión was.
The street belongs to the colonia de El Viso, the rationalist complex that Rafael Bergamín built between 1933 and 1936 on one of the high ridges of northern Madrid. Most of the streets that thread through its white villas were given the names of rivers: the Tajo, the Ebro, and the Genil, alongside several from the Basque Country and Navarre, such as the Bidasoa and the Urumea.
Among those river names, Emilio Campión is an exception: a surname, not a river. Campión is a Navarrese surname, famous through Arturo Campión, a jurist and philologist from Pamplona who defended the Basque language. But the plaque names an Emilio, and of that Emilio no reliable trace has survived.
