Coca Castle is one of the best preserved castles in Spain. It was constructed in the 15th century with visible brick masonry, amply embellished (Mudejar style) with pinnacles and turrets. It was the bastion of the powerful Fonseca family. The wide ditch is not designed to be filled with water, but rather to serve artillery purposes. Today, the castle houses a college for forestry. The castle is also a popular tourist destination.
