Calle de Aguilón
The name recalls Aguilón, a small town in the Campo de Cariñena, in the province of Zaragoza, though no record survives of why it was chosen for this street in the Chopera neighbourhood.
Aguilón is a village in the province of Zaragoza, set in the bottom of a ravine of the Iberian System, in the district of Campo de Cariñena. Scholars trace the place name to a Roman estate belonging to someone called Aquilo, whose name, reshaped over the centuries, would have become that of the town. Why that Aragonese place name travelled to this corner of Arganzuela is not documented.
The word has a life of its own in Spanish. Aguilón is the augmentative of eagle, and from there it passed into the building trade: it is the name of the beam that runs diagonally from the corner of a roof frame, and also the swivelling arm of a crane, that jib seen turning over building sites.
The street runs through the Chopera neighbourhood, which took its name from the poplar groves that grew beside the Manzanares before the river was tamed.
