The Castillo de Tejeda y Segoyuela stands as a 15th-century defensive fortress in the province of Salamanca, constructed in 1453 by the nobleman Fernando de Tejeda. Built with a square plan featuring approximately 23-meter sides, the castle was designed not to defend against external invasion but rather to consolidate the lord's civil and criminal jurisdiction over his territories. The structure comprises a large rectangular tower, a barbican, and surrounding walls with corner towers, originally equipped with cannon loopholes and wooden-floored chambers. Though designated a Cultural Heritage Asset, the fortress faces significant challenges from weather exposure, invasive vegetation, and vandalism, which threaten its historical integrity.
