This is the Olexandrivska belltower of the Dormition Cathedral in Kharkiv. Its construction was timed to the victory over Napoleon in 1812, and it was named after Tsar Alexander I of Russia. The author of the project – the architect Evgen Vasyliev died before it was finished. After his death, the construction was supervised by Andriy Ton and completed in 1844. In 1924 the first radio antenna in Ukrainian was installed on the belltower. Since then, in Ukraine the Radio and Communications Workers' Day is celebrated on November 16th.
