The church of Vihanti was completed in 1784 to replace the first one built in 1691. It is designed by Simon Silvén. The interior of the wooden cruciform shape church is decorated by Emanuel Granberg and Erik Westzynthius. The altarpiece is painted directly to the log wall. The bell tower (1752) originates from the earlier church.
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.
