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.
References:Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
