Ostankino Palace is a former summer residence and private opera theatre of Sheremetev family. Extant historical Ostankino includes the main wooden palace, built in 1792-1798 around a theater hall, with adjacent Egyptian and Italian pavilions, a 17th-century Trinity church, and fragments of the old Ostankino park with a replica of Milovzor folly.
Ostankino Palace is the real gem of Russian art of the 18th century, where the theatrical room with a stage, auditorium, makeup rooms, architecture, sculpture, painting, graphics and decorative art are in unison. The palace was built according to the plan and order of Count Nikolai Petrovich Sheremetev - one of the most distinguished and wealthy people of his time. Sheremetev was passionate about the theater, had a magnificent troupe of serf actors, so the heart of the summer residence was a theater with a unique theatrical machinery. The interiors of the main halls have preserved the original decor and decoration. Special elegance is attached to the halls of lighting fixtures made of crystal, bronze, gilded carved wood. Construction continued from 1792 to 1795, although the first projects date back to 1790, and the final decoration by 1799.

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.
