Boo fideikommiss (estate in tail) was founded in 1735. The first owner was one of the generals of the Swedish king Charles XII, baron H. J. Hamilton. After imprisonment in Russia he took up residence at Boo. Thereafter the estate has been inherited within the family Hamilton af Hageby. The current Boo Castle was built to the grounds of older manor house in 1874-1882. The Neo-Gothic building was designed by Johan Fredrik Åbom. Boo was the a residence of Hugo Johan Hamilton af Hageby. Today it is still a private residence.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.
