Blois Cathedral (Cathédrale Saint-Louis de Blois) is a Roman Catholic cathedral, and a national monument of France, in Blois. It is the seat of the Bishopric of Blois, established in 1697.
This was previously the collegiate church of Saint-Solenne, the original building of which dated from the 12th century. Apart from some traces in the crypt nothing survives of this. The façade and the bell tower were built in 1544. The nave was destroyed by a hurricane in 1678, and the reconstruction in Gothic style took place between 1680 and 1700 under the architect Arnoult-Séraphin Poictevin (d. 1720). The Lady Chapel by the architect Jules Potier de la Morandière was added in about 1860.
To celebrate the church's elevation to a cathedral in 1697, Louis XIV presented the organ loft in 1704. The new see thereupon took the dedication to Saint Louis.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.
