I really love the city of Semyonov because you can see many different sights, old buildings and monuments there. But I would like to devote my attention to the Museum of History and Art. The Semenovsky Museum of History and Art was founded in 1934 by the artist Georgy Petrovich Matveev. The exhibition halls of the museum were originally located in an old two-story building located on Matveev Street. In 1991, a two-story red brick mansion on ul. Vaneeva, built at the end of the 19th century and previously owned by the merchant-Old Believer Pyotr Petrovich Sharygin.
