For over 700 years Örebro Castle has kept a watchful eye on everyone crossing the bridge on the River Svartån. The oldest part of the castle, a defence tower, was erected in the latter half of the 13th century. This tower was added to in the 14th century to make a larger stronghold. The castle was expanded during the reign of the royal family Vasa between 1573-1627 to the impressive Renaissance castle.
After Vasa family Örebro castle was left to decay, but the main restoration took place in 1758-1764 by Carl Johan Crondstedt. After him the castle was used as a residence of county governor. The castle was finally restored to the 16th century appearance between 1897-1900.
Today there are guided tours, an exhibition centre and the castle is a very worthwhile sightseeing destination.
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.
