This building is also known as the Castillo de los Marqueses de Casablanca. It is a 19th century manor house. After the confiscation of Mendizabal it was purchased at auction by the Countess de Antillon. It has a walled garden with tall trees from where you can see the four graceful towers of the building. It was the summer residence of the family until in 1914 when it was acquired by the town of Deifontes.
