of Russia. Abandoned both by the original owners and by the Russian army, the palace gradually fell into disrepair. However, it was restored by the Radziwiłłs and between 1881 and 1886 the castle's interiors were renovated by Prince Antoni Wilhelm Radziwiłł and his French wife, Marie de Castellane. They also designed a landscape park in English style. With an area of more than one square kilometre, the park is one of the biggest such facilities in Europe. After the Polish–Soviet War the castle complex and the surrounding area became part of the newly established Second Polish Republic in 1920. During that time, the castle was considered one of the most beautiful in the Kresy region. During the invasion of Poland in 1939, the Radziwiłł family was expelled from the castle by the Red Army. In Soviet times, the castle was used as a sanatorium, while the park gradually fell into neglect. The castle complex is considered to be the most beautiful in Belarus. In 2005 it was listed by UNESCO as a World Heritage Site. The castle complex was extensively restored from 2004–2012.
