The Mir (Mirsky) Castle Complex was listed as a UNESCO World Heritage site in 2000. Duke Yuri Ilyinich began construction of the castle near the village of Mir after the turn of the 16th century in the Gothic architectural style. Five towers surrounded the courtyard of the citadel, the walls of which formed a square of 75 meters on each side. In 1568, when the Ilyinich dynasty died out, the Mir Castle passed into the hands of Mikołaj Krzysztof 'the Orphan' Radziwiłł, who refitted it with a two-winged, three-story stately residence along the eastern and northern inner walls of the castle. Plastered facades were decorated with limestone portals, plates, balconies and porches in the Renaissance style.
In 1817, after the castle had been abandoned for nearly a century and had suffered severe damage in the Napoleonic wars, owner Dominik Hieronim Radziwiłł died of battle injuries and the castle passed to his daughter Stefania, who married Ludwig zu Sayn-Wittgenstein-Berleburg. Later the castle became a possession of their daughter Maria, who married Prince Chlodwig Hohenlohe-Schillingsfürst.
Their son, Maurice Hohenlohe-Schillingsfürst, sold the castle to Nikolai Sviatopolk-Mirski, of the Bialynia clan, in 1895. Nikolaj's son Michail began to rebuild the castle according to the plans of architect Teodor Bursze. The Sviatopolk-Mirski family owned the castle until 1939, when the Soviet Union occupied eastern Poland.
When German forces invaded the Soviet Union in 1941 they occupied the castle and converted it to a ghetto for the local Jewish population, prior to their liquidation. Between 1944 and 1956, the castle was used as a housing facility, resulting in damage to the castle's interior.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
