Chelyabinsk

Archaeologists have discovered ruins of the ancient town of Arkaim in the vicinity of Chelyabinsk, indicating a relatively advanced civilization since the 2nd millennium BC.

During World War II, Chelyabinsk was informally called 'Tankograd' due to its production of tanks and ammunition.

Chelyabinsk is said to be located on seven hills, similar to cities like Rome and San Francisco.

Chelyabinsk's largest public library, the Chelyabinsk Regional Universal Scientific Library, has more than 2 million books.

The Chelyabinsk Zoo participates in international programs for the conservation of endangered species, including Siberian tigers and polar bears.
