The town of Nogales was incorporated into the lordship of Feria in 1395 after its purchase by Gómez I Suárez de Figueroa, the first lord of Feria. In the mid-15th century, the repopulation of the locality began, and the construction of the castle to protect its inhabitants commenced.
Above the gate of the homage tower, you can find a coat of arms of the Figueroa family and another of the Manuel family, along with an inscription indicating that the fortress was built by the order of Lorenzo Suárez de Figueroa, the son of Gómez Suárez de Figueroa, in 1458.
On the gate of the walled enclosure, there are two more coats of arms, one of the Figueroa-Manuel family and another of the Osorio and Rojas family. These coats of arms were placed in 1464 by Gómez Suárez de Figueroa, the son of Lorenzo Suárez de Figueroa.
The military use of the building continued over time and was employed during conflicts with the French and Portuguese. Although it did not fall into a state of ruin, the passage of time and neglect deteriorated the structure until the Junta de Extremadura decided to restore it in the late 20th century.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
