The Livonian Order's stone castle is the oldest building in Dobele, and a national architectural monument. It was built on the site of an ancient Semigallian timber fortress from 1335 to 1339. A church was built and a park was laid out later.
This land hosted a settlement of Dobele's most ancient inhabitants – the Semigallians as early as 1000 years B.C. Surrounded by the ancient town, there stood a timber fortress, one of the administrative centres of ancient Semigallians. The castle has been mentioned several times in the Livonian Rhymed Chronicle telling about the 13th century battles between the locals and the German crusader knights. Between 1279 and 1289, Dobele castle withstood six enemy attacks. In 1289, the Semigallians burnt down their fortress and left, undefeated, for Rakte in Lithuania.
Until 1562, the castle was headquarters for the chief of the garrison and also the Komtur, commander of the district. During the period of the Duchy of Courland and Semigallia, several commanders were in charge of the castle, the last one being Christoph Georg von Ofenberg. After 1729, the castle built by the Order was abandoned and gradually fell in ruins. Works for the conservation of the ruins started were launched in 2002.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.
