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:
The Peace Palace (Vredespaleis) is an administrative building and often called the seat of international law because it houses the International Court of Justice (which is the principal judicial body of the United Nations), the Permanent Court of Arbitration, the Hague Academy of International Law, and the extensive Peace Palace Library. In addition to hosting these institutions, the Palace is also a regular venue for special events in international policy and law. The Palace officially opened on 28 August 1913, and was originally built to provide a symbolic home for the Permanent Court of Arbitration, a court created to end war which was created by treaty at the 1899 Hague Peace Conference.
