Pažaislis monastery and church form the largest monastery complex in Lithuania, and the most magnificent example of Italian Baroque architecture in the country. Founded in 1662 by the Grand Duchy of Lithania Great Chancellor Krzysztof Zygmunt Pac for the Order of the Camaldolese Hermits, the main construction continued until 1674 and resumed in 1712. The church was designed by Pietro Puttini, Carlo and Pietro Puttini, and Giovanni Battista Frediani. In 1755 the addition of the towers and the dome was funded by the king's chamberlain Michał Jan Pac.
In 1832 the church was closed by the Russian authorities and later converted into an Orthodox church. The author of the Imperial Russian national anthem God Save the Tsar, Alexei Lvov, was interred there in 1870. After 1920 the ruined church returned to Roman Catholics and was restored by sisters of the Lithuanian convent of St. Casimir. After World War II, the Soviet authorities converted the church and monastery into an archive, a psychiatric hospital and finally an art gallery (in 1966). In 1990s the complex was returned to the nuns of the convent and reconstruction work began.References:
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.
