Hyrynsalmi church was built in 1786 and it was designed by Jacob Rijf. It is one of the most significant wooden churches built in Finland in the 18th century.The separate bell tower was erected in 1840. The altarpiece painted by J. G. Hedman dates back to 1830.
During World War II corpses from the Suomussalmi battlefield were brought into this church to be returned to their home parishes for burial. The church is one of the few buildings, which survived when German troops burnt the village in the Lapland War (1944).
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.
