The manor house with the mysterious name ""The Round Court"" is located in the city of Trostyanets, Sumy region. The first owner of the estate, Tymofiy Nadarzhynsky, was the clergyman of Peter I. For his loyal service, tsar granted him land in Trostyanets, where he and then 4 of his sons worked on the development of the estate. The next owners were Golitsyns. Around this time the fenced yard began to be used as a home circus, where serfs' performances and circus concerts were organized. Today, festivals take place in the courtyard, the most famous of which is East Rock, founded in 2013.
