The cliffside village of Arcos De La Frontera is in the Spanish province of Cadiz. It’s one of Andalucia’s pueblos blancos, or white villages, known for its many whitewashed buildings. The village sits on a limestone cliff above the Guadalete River. With a source of fresh water and the hilltop location allowing defensive views of anyone approaching, it was an ideal spot for a settlement. It’s been occupied for a very long time—artifacts and ruins have been found there that date to the Neolithic and Bronze Age, as well as from the Phoenician, Roman, and Moorish periods.
