Brunswick Palace (Braunschweiger Residenzschloss) was the residence of the Brunswick dukes from 1753 to 1918.
Work on the first building was begun in 1718 under the direction of Hermann Korb. After the building burned down in 1830, a second palace was built by Carl Theodor Ottmer, being completed in 1841. It was completely demolished in 1960 at the direction of the city council because of the heavy damage that it had suffered in air raids during the Second World War.
The exterior was rebuilt to contain a palace museum, a library and a shopping centre, which opened in 2007.
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.
