Ruzhany Palace is a ruined palace which was between the 16th and 19th centuries the main seat of the senior line of the Sapieha noble family. Ruzhany began its life in the late 16th century as the site of Lew Sapieha's castle, the palace being completed in 1602. The Sapieha residence was destroyed in the course of the internecine strife in the Grand Duchy of Lithuania when it was attacked by Michał Serwacy Wiśniowiecki's forces in 1700.
Ruzhany Palace was rebuilt as a grand Neoclassical residence in the 1770s by Aleksander Michał Sapieha, employing the services of the architect Jan Samuel Becker of Saxony, who set the palace in an English park landscape. Aside from the palace, there was a theatre (1784–88), an orangery and several other outbuildings. Becker also designed the local church (rebuilt in the 1850s).
By the time of King Stanisław II's visit in 1784, work on the palace had been suspended. The Sapieha estates were nationalised in the aftermath of the November Uprising (1831). Three years later, the palace compound was sold to be used as a textile mill and weaving factory.
In 1914 the palace was accidentally set on fire by factory workers. The First World War and subsequent financial hardships prevented the building's restoration until 1930, however the partially restored palace became a ruin again within fifteen years, a casualty of the Second World War. The ornate palace gate survives and has recently been restored.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
