Peñafiel, Spain

Peñafiel is a town in the Valladolid Province and the greater autonomous community of Castile and León, Spain. It is best known for the Peñafiel Castle and for its medieval square used for bullfights and named "Plaza del Coso". The square is surrounded by private homes, but since medieval times the rights to use their windows, balconies and doorways during bullfights are owned by the town, which auctions them to the highest bidders.

The town is full of deep excavated caveswhich were traditionally used to store the wine because of the constant temperature they kept all year around. These caves have chimney vents for ventilation and to evacuate the gases generated by the fermentation of the wine. These chimney vents dot the landscape in and around the town and the castle.
