Segura de la Sierra
This small village, in the province of Jaén in eastern Andalusia, has a dramatic setting on a hilltop, its whitewashed houses seeming to cling precariously to the hillside. It was an important location during the Arab rule of Spain, when Moorish leaders built the walls that surround the town. The jewel in the crown of the village is its Mudéjar Castle, which sits high on top of the hill looking down on the village, surrounded by ancient walls.
