"Most Spanish towns faced with Cuenca's need to expand in the 18th century would have spread out along the surrounding countryside. But Cuenca, perched on the top of a hill, turned not to the earth but to the sky. Its improbable solution stands all along that part of the town that clings to the side of the hill and that faces the River Huécar: its hanging houses. The flat-fronted dwellings in the Barrio de San Martín, so starkly simple a child could draw them, rise seven or eight teetering stories above a ravine and the River Heucar to the east. It is as if the town were trying to outgrow itself, reaching ever higher in an effort to compensate for the ravine below."
-- Isabel Soto, "Hanging Houses of Cuenca," The New York Times
