Monasterio de San Salvador in Cornellana is a monastery located in the municipality of Salas. Consisting of several Romanesque style buildings which started to be built in the 11th century, the monastery was founded by infanta Cristina Bermúdez, daughter of Bermudo II of León and his first wife Queen Velasquita Ramírez. She founded the monastery in 1024 after the death of her husband, infante Ordoño Ramírez 'the Blind', son of Ramiro III of León and his wife Sancha Gómez. Cristina lived in the monastery as a nun and was buried there.
After her death, the monastery was divided among her heirs, her sons and daughters; Alfonso, Aldonza, Ordoño, and Pelaya Ordóñez. A great-grandson of Cristina, the powerful Count Suero Vermúdez in 1120 donated the monastery to the Abbey of Cluny and then to the Cathedral of Oviedo.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
