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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
