Castle of Zafra in Campillo de Dueñas

You're standing at the Castle of Zafra, high in the Sierra de Caldereros, at around 1,400 metres. Start by looking at the rock itself. The castle sits on top of a long, weathered ridge of sandstone and fills it completely. At the south-west end is the entrance tower, at the other end the main buildings, with a wall linking the two. Now glance at the meadow around you. Those traces of buildings may be stables or storehouses from an outer enclosure.
