Châtelard castle was built probably by Rudolph Grossi, bishop of Aosta in 1243 and archbishop of Tarantasia in 1246. It is first mentioned in a document from 1248, and presents the type of circular tower reminiscent of the fortified constructions of Count Peter II of Savoy, to whom Grossi was a close advisor. All around, medieval dwellings of all shapes and sizes dot the land like small sentries with an ancient charm: the Pascal fortified house, the Aragon fortified Manor house, Maison Gerbollier, just above, the home of the Ecours and again, in the village of Derby, the notarial castle.
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.
