Calle de Jiloca
Takes its name from the river Jiloca, an Aragonese tributary of the Jalón whose name comes from Andalusi Arabic.
The name comes from a river in Aragón. The Jiloca runs some 126 kilometres between Teruel and Zaragoza, from the Ojos de Monreal del Campo to where it flows into the Jalón near Calatayud. Its flow is irregular, with autumn and spring floods and a harsh dry season, typical of the parched lands it crosses.
The place name comes from Andalusi Arabic šalawq, “sea wind”, the same root that gave Castilian jaloque and Catalan xaloc, names for the wind that blows from the southeast, owing to the course’s orientation towards that point of the compass. Medieval documents write it Xiloca or Exiloca as early as 1328.
The Calle de Jiloca belongs to the Hispanoamérica district of Chamartín, a layout drawn largely during the 20th century, thick with the names of Iberian rivers and landforms. Here a Teruel tributary names a Madrid street more than two hundred kilometres from its valley.
