Villavellid Castle is located on a little hill next to the village. By its diposition and characteristics it can be dated to the 15th century and it was probably the residence of a nobleman. Its constructor isn't known although in 1452 a Don Francisco de Almazán, Marquess of Alcañices, was mentioned as the Lord of the village and the owner of a 'strong house'.
Its plan is a square with wide walls of ashlar masonry on the outside. The corners are reinforced by cylindrical towers except one which is reinforced by the square keep which is very reduced at the present time. This all makes the castle in everything very similar to Fuente el Sol Castle. The entrance to the courtyard is by a pointed arced gate, located near the keep. The entrance to the keep is on a higher floor level and would have been accessed by means of a, disappeared, movable wooden footbridge. Inside the tower several wooden floors existed. Also traces of lean-to constructions are observed in the walls around the courtyard.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
