The Church of Great Saint John the Baptist was built as a Gothic style fort-church probably in the end of 13th century but before 1330's. It is a typical Central-Estonian church with three naves. There is a rectangular east choir and tetragonal west tower. The portals of the church are remarkable. During the wars the pillars and arches of the church were destroyed. Supposedly, the church had round pillars. The wooden ceilings were built when the church was reconstructed.
Late baroque organ prospect (by Johann Andreas Stein, 1804) covers the organ made by the Kriisa brothers in 1937. The altar wall dates back to 1870 and was created by Johann Gottfried Mühlenhausen. The altar painting of church is “Jesus Christ on the Cross”. There is a monument of Hans Heinrich von Fersen, a memorial plaque for Alexander von Fersen, and a unique cross from 1598, one of the oldest in Estonia, in that 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.
