Château du Bousquet was built in the 14th century. Today it hosts a museum of ancient art from the Middle Ages to the present day. The castle has very well-preserved sample of late medieval architecture (furnished interior, furniture, objects, paintings).
The castle, which belonged for four centuries to the Roquefeuil-Blanquefort family, comprises six towers (two hexagonal in the middle of the two front and rear facades, four rounds at each corner). The central tower of the south facade, which contains the staircase is pierced on the ground floor of a radiating Gothic door. The typically feudal and defensive character of the castle is somewhat mitigated by the existence of later windows on the three floors. The defensive system which surrounded it (enclosure, ditch, fortifications) disappeared, replaced by two wings in the 17th century. Inside, the ground floor has kept its kitchen intact, with the mesh stage where the musicians were based. The chapel retains a decoration painted by Debert in 1709.
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.
