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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
