The Abbots' Palace (Pałac Opatów w Oliwie) is a roccoco style palace in Oliwa. The first portion of the palace, the 'Old Palace' was constructed in the 15th century. Later, in the first half of the sixteen hundreds a 'New Palace' was added, which served as the residency of the then abbot of the Cistercians, Jan Grabiński. The final additions to the palace were made between 1754 and 1756, and were funded by another Cistercian abbot, Jacek Rybiński.
After the partitions of Poland the area became part of Prussia, in 1831 real estate of the Cistercians was secularized and the palace became property of the House of Hohenzollern. From 1796 until 1836 the Bishops of Ermland (Warmia), Karl von Hohenzollern-Hechingen and Joseph von Hohenzollern-Hechingen resided in the Palace. It remained empty until 1869 when Maria Anna von Hohenzollern-Hechingen, niece of Joseph, took up residence there. After her death in 1888 the ownership of the palace was taken over by the city of Oliva, which used it for offices and apartments.
During the interwar period of the Free City of Danzig the palace contained a museum which housed exhibitions on the history of the region. The director in charge of the of the museum was a Nazi activist named Erich Keyser.
In 1945, at the end of World War II (during which time it served as an arms depot) it was set on fire by German troops who sought to clear the terrain in front of the advancing Red Army. The palace was rebuilt in 1965 through the efforts of the Pomeranian Museum in Gdańsk. It initially served as the ethnographic department of the museum. In 1972 the Museum was elevated to a status of a National Museum.
Since 1989 the palace contains the Department of Modern Art of the Polish National Museum in Gdańsk. In February 1990 a special gallery devoted to contemporary Polish art was established. Permanent exhibitions include works by Polish artists from 19th and 20th century (painting, sculpture and ceramics). It also houses the 'Promotional Gallery' which exhibits works by young artists.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.
