Castle of Los Zúñiga was built in the 15th century by D. Pedro de Zuñiga. Its objective was to defend the passage of Barca del Río Piedras.
Its structure is rectangular in shape and consists of a wall circuit with seven square towers at the corners and on the front and side canvases. The most important towers are the bell tower and the homage tower. In addition to these towers, there was a second outer low wall, already disappeared.
In the 16th century the castle was refortified. Barbican was added, which was specially conditioned. It was an ideal refuge for citizens before the attacks of the Portuguese occurred in the 17th century and ended up consolidating the current town.
In the 18th century, it was planned to convert it into a barracks for the guard corps but discarded the project ended abandoned in 1812.
In 1815, the Duke of Béjar transferred the property to the Villa. In 1817, it was disarmed and adapted for cemeteries, dismantling the barbican and building barracks of vaults attached to the walls inside. He kept this use up to 1,872. Then it was destined to deposit coals and wood, after its desacralization.
In 1880 the file for the demolition is instructed, for its state of ruin, which is understood to threaten to collapse, and the corpses that are still preserved in the vaults, not those on the ground, are exhumed. As on other subsequent occasions, the demolition was not carried out due to the difficulties involved, acting simply to consolidate the most dangerous.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
