Château de Lauquerie is a former fortress built in the 14th century by the Templars, erected to defend the borders of the Dordogne and the village of Lauzun. It was offered by Henri IV to his squire Sire François de Longueval for having served him faithfully for 30 years. Remained for several decades in the Longueval family, it was partially destroyed during the French Revolution, then became the property of the Lajaunie family from 1889 to 1989. Completely renovated in the 90s, it is nowadays a private residence converted into tourist accommodation.
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.
