|Trostianets (22,000 residents) is a regional center, located on the banks of Boromlia River. The Right-Bank migrants founded Trostianets in the mid-17th c.; for the first time written records mentioned it in connection with erection of a church in 1660. In 1720, Russian Tsar Peter I presented the city to his confessor T. Nadarzhynsky, whose manor passed into the hands of princes Golitsin at the end of the 18th c. All surviving landmarks were built when they held the reins. The oak forest on the bank of the pond gave way to a park at the end of the 18th c. The palace, buildings, grotto and other park buildings emerged in the beginning of the next century. The downtown mannge arena was built in the 1820s. It is the only surviving structure of this kind in Ukraine; it looks more ascetic now, though. It was a multifunction structure: the citizens used it as utility premises, mannge and theater in the open, where ballets and circus performances were staged. There is a manor house nearby, where P.Tchaikovsky lived in 1864 The surviving buildings for public worship were built in different styles, though in the same period. The Church of Annunciation (early 19th c.) boasts 40-meter belltower and skilful work of masons; the Church of Ascension (1913) is a plump temple with the classical belltower. In the park of Trostianets (256 ha) there are over 200 types of trees and bushes, including even exotic kinds. The most striking are majestic 200-300-year-old oaks several meters in circumference.
