History
Lagunas Rubias Castle is the ruined remains of a medieval fortification in Spain, near the former settlement of Lagunas Rubias, now within the municipality of Aldeanueva de Figueroa in Salamanca. The Kingdom of León commissioned it during the twelfth or thirteenth century as a calicanto fortification, using lime-bound masonry formed within temporary supports, to defend its frontier against the Kingdom of Castile.
The Leonese frontier system
The castle belonged to the Territorial System of Fortifications, a planned network of newly built defensive enclosures created during the separation of León and Castile between 1157 and 1230. Its development took place under Ferdinand II and Alfonso IX of León, and under Alfonso VIII, Berengaria, and Ferdinand III of Castile. The fortification also helped address later threats from the Kingdom of Portugal and the Almohads, a North African Islamic dynasty whose expansion affected the Iberian Peninsula during the twelfth and thirteenth centuries.
During 73 years of dynastic warfare between the Castilian and Leonese monarchies, Lagunas Rubias Castle was expanded successively. It acquired a place within a defense-in-depth strategy, in which multiple fortified positions supported one another across a frontier rather than relying on a single stronghold.
Abandonment and later history
León and Castile were unified under Ferdinand III in 1230. After the union, fortifications that had become obsolete were abandoned, while some defensive elements were deliberately disabled or destroyed. Certain positions were briefly reused during conflicts connected with the minorities of Ferdinand IV and Alfonso XI.
Lagunas Rubias Castle is listed as having been destroyed in the nineteenth century by the Napoleonic army. Its remains have generic legal protection under the decree of 22 April 1949 concerning Spanish castles and under Spain’s Historical Heritage Law 16/1985.
Remains
Frontier enclosure
The site consists of the ruined remains of a medieval castle standing west of the houses of the Lagunas Rubias estate, in the area associated with the former settlement. It belongs to a Leonese frontier-building tradition of newly constructed fortified compounds, including castral enclosures organized in the manner of castles and ovoid enclosures with egg-shaped plans. These defenses used calicanto formwork masonry, producing compact walls within a prepared framework.
The listed area of the castle is 263 square metres, and the surviving remains reach a stated height of 1.85 metres. The fortification is currently in progressive ruin, preserving part of the structure that once formed a Leonese defensive position along the contested frontier.
