Šlokenbeka Castle is a fortified manor and the only existing example of a fortified manor centre in Latvia. The construction was started by the Livonian Order before 1544. It was built in a trapeze-type yard, which was enclosed with stone walls and portholes. In 1772 the attic roofs were added to the building.
In the 17th century towers with portals and weathervanes were erected, but Šlokenbeka lost its defence function, being then adapted for domestic purposes. At the end of the 18th century new buildings were built and old buildings were renewed. New gate towers were added at the north and south walls. Between 1841 and 1845, a new manor house in classicist style was built at the north wall. In the 1930s Šlokenbeka lost some of its buildings. During Soviet times it housed the 5th road maintenance unit. Now it contains the Latvian Road Construction History Museum and a restaurant.
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.
