This historic monument, declared a Cultural Heritage Asset in 1949, retains strategic views of the surrounding landscape and offers insight into medieval Galician defensive architecture.

Castelo de Doiras stands as a magnificent 15th-century fortress perched at 700 meters in the Sierra de Os Ancares mountains near Cervantes, Lugo. This rectangular structure, measuring 25 by 21 metres, features thick slate masonry walls 1.5 metres thick and rises to 8 metres high, crowned by a 16-metre tower of homage in perfect condition. Built by Paio Guindós to defend the Camino de Santiago, the castle was originally held by the Moirón family before passing to the Count of Grajal de Campos. Today, restored and opened to the public by the Concello of Cervantes and Deputación of Lugo, it commands stunning views over the Cervantes and Doiras rivers.

Castelo de Pobra, also known as Castro da Pobra de Parga, sits in ruins in Guitiriz, Galicia, along the Way of Saint James pilgrimage route. Built in the late 14th or early 15th century, this fortress was constructed to monitor the ancient road connecting Lucus Augusti to Flavaia Brigantium. The castle was built atop the remains of Roman constructions, integrating older defensive principles with medieval architecture. Today, only portions of the enclosure wall and a cylindrical tower approximately four meters in diameter remain, though these preserve significant architectural elements of medieval and Roman origin.
