Nydala Abbey was a medieval Cistercian monastery. Nydala (from Swedish ny, meaning new, and dal, meaning valley) was called Sancta Maria de Nova Valle or just Nova Vallis in Latin. It was founded together with Alvastra Abbey in 1147 as the first cistercian monasteries in Sweden. King Gustavus Vasa appropriated the abbey in the 1520s, and the Danes sacked it in 1568. Part of the abbey church was rebuilt in the following years, and is still used as parish church. Some other ruins also remain visible at the site.
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.
