Western Andalusia is well known for the production of sherry. Jerez de la Frontera, which lies thirty-six kilometres north-east of Cádiz, is most famous for the production of this fortified wine. In addition to its 11th-century alcázar, built around a mosque, and its cathedral with its painting by the master Zurbarán, Jerez is also famous for its Real Escuela Andaluza de Arte Ecuestre where public dressage displays are held. As one might expect, Jerez has a number of wine cellars, known in Spanish as bodegas, which can be visited on your Spain tour.
