Magnificent Coca Castle was built in the 15th century by Alonso de Fonseca, a mighty archbishop of Seville, during the reign of King Enrique IV of Castile. It's made up of two square baileys separated by a passageway. Both show polygonal towers at the corners. The double walls are 2.5 m thick and it's circled by a deep dry moat.
Coca castle is a mixture of western and Moorish military architecture, as can be seen from its decoration. It has a square ground plan, a moat and two walled enclosures, which gives it the air of impregnability for which it has been known over the centuries. The keep is located in the second area. It is made of brick and its walls are profusely decorated. The interior is very luxurious and lavish, and conserves its Mudejar decoration. Due to its great splendour, it was used more as a palace than as a fortress. It is one of the crowning works of the military Mudejar style.
The castle is owned by the Alva family and now serves as a training center for foresters. Their school is situated in the inner bailey.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
