Coria Castle was constructed by architect Juan Carrera, between 1473 and 1478, by order of García Álvarez de Toledo (died 1488), Duke of Alba and first Marquis of Coria. Located to the northwest of the Roman City Walls, this work of military engineering was constructed in place of another fortification occupied by the Knights Templar in the 12th century. It has an irregular pentagon layout, like a starling, which projects from the walled enclosure and was built with fine masonry of perfectly dressed and squared granite ashlars.
The Keep is completed by what is popularly known as Castillejo: a small crenellated structure within the city walls that is equipped with a bent entrance and a drawbridge. It was defended through a circular casemate tower and an extensive moat constructed by Tomás Bretón in 1473, which is partially visible today. Crowning the entire fortified complex is the continuous band of the cornice of balls or knobs placed in the blind arches over the corbels surrounding the entire perimeter of the battlements in the Late-Gothic or Elizabethan style.
Today, the interior of the Castle of the Dukes of Alba is not open to the public since it is private property, however, visitors can explore its surrounding area or exterior space.
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.
