Olvera is a municipality in the province of Cádiz in Andalusia ( southern Spain ), located on the Ruta de los Pueblos Blancos ( White Villages ).

On the highest elevation in the middle of the village there is a parish church, which was built on the remains of a Moorish mosque and a ruined castle. Both are exclusively surrounded by low white rows of houses that make up the character of the village.

The landscape around Olvera is dominated by agriculture, mainly through olive groves and grain fields.

At the time of the Middle Ages Olvera was a station on the smugglers road from Ronda to Morón de la Frontera.
