Alberga Manor was first mentioned in the 1620s. The current main building was built as a summer residence by council Feodor Kiseleff in 1874–1876. Later it was in the possession of Helsinki city and left to decay. The main restoration was made in 1997 and today Alberga is used by Espoo City culture office.
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.
