Zahara de la Sierra is municipality in the province of Cádiz in the hills of Andalusia, southern Spain. It is perched on a mountain, overlooking a valley and a man-made lake formed by the dam that must be driven over to access the town. It is considered to be one of the "pueblos blancos" or "white towns" because the overwhelming majority of the buildings are white.

The town was originally a Moorish outpost, overlooking the valley. Due to its position between Ronda and Seville, it was a perfect site for a castle to be built to serve as a fortress in case of attack. The remains of the Moorish castle are still existing.
