The medieval church of Mihkli (St. Michael) was originally known as Soontagana church. It was built already in the end of 13th century. The present stone-made bell tower was added in 1779-1787. The interior is mainly from the 19th century with the exception of medieval font pedestal and bell made in Stockholm in 1684.
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.
