Monzón de Campos Castle was built in the 14th century by the Rojas family on the remains of an earlier castle which was contemporary one. The keep, made of high quality ashlar masonry, has no openings besides a couple of small arrow slits which gives it a severe appearance.
The oldest part is the elevated entrance of the present tower of homage.The coat of arms on the pointed arch of the main gate belongs to the Rojas family.
Inside, the castle has not preserved the original distribution except in the tower. A Romanesque door was added to the tower of homage. It was brought in from a church that had been covered by the water of the dam in Aguilar de Campoo. The village of Monzón, with its castle, was the centre of a county donated to the Ansúrez family by the kings of León during the 10th and 11th centuries and in the 15th and 16th centuries it was owned by the Rojas, a family from Burgos that since 1530 had the title of Marquises of Poza. They are likely to have built the present castle in Monzón de Campos.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
