Valley of Dreams Curiosity · Puebla de la Sierra, Sierra Norte, Madrid Image of Puebla de la Sierra, not of the place itself. An open-air museum born of a sculpture workshop held in the village in 1998: more than a hundred works by dozens of artists spread over some two kilometres between the church square, the hermitage and the bridge over the river.
