The medieval church of Mihkli (St. Michael) was built probably in the end of 14th century. It was mainly destroyed in several wars until the restoration began in the 19th century. The wooden bell tower was built in 1863 and the church was restored to the neo-Gothic appearance in 1901 using medieval walls.
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.
