Castle of Narros de Saldueña, Medieval fortress in Narros de Saldueña, Spain.

The Castle of Narros de Saldueña, also called the Castle of the Duke of Montellano, consists of a single rectangular tower and an adjoining rectangular fortress that completes the ensemble. The tower, built before the fortress, bears the coats of arms of the Valderrábano and Guzmán families. Its style broadly follows the Valladolid School.

The fortress was built in the 15th century by Rodrigo de Valderrábano, a regent of Ávila who held significant regional influence. The building later endured occupation by French forces during Spain's War of Independence.

The castle displays coats of arms belonging to the Valderrábano and Guzmán families, marking their connection to local power. These heraldic symbols reflect the social hierarchies that shaped life in this region during medieval times.

The castle stands in Narros de Saldueña, in the province of Ávila, within Castile and León. The site is reached from the surrounding small villages of the Moraña plain, so a vehicle and local directions are useful. The tower and the adjoining rectangular fortress form a compact group that can be viewed from outside.

The castle is also known as the Castle of the Duke of Montellano, a name that recalls a later noble title rather than its 15th-century builder. Its single rectangular tower carries the arms of the Valderrábano and Guzmán families and was raised before the adjoining rectangular fortress that completes the complex.
