Landestrost Castle in the Weser Renaissance style that was built between 1573 and 1584 in Neustadt am Rübenberge in the north German state of Lower Saxony. Integrated into fortifications, together with the town, it developed into an urban fortress typical of the 16th century. The castle was the representative residence and administrative headquarters of Eric II of Brunswick-Lüneburg. During its construction period from 1574 he renamed the town of Neustadt as Landestrost, something which was reverted after his death in 1584.
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.
