The children's quest transforms the museum exhibition into a map of old Yekaterinburg. Kids will learn why the city was called the "Mountain Kingdom," how coins were minted here, gemstones were processed, factories were built, and new entertainments were explored. Tasks and a film will help gather scattered facts into a coherent story and feel like explorers of the 19th century. Two hundred years ago, Yekaterinburg was perceived as a special world with its own riches, rules, and pace of life. It was called the "Mountain Kingdom," the "Golden City," and even a "state within a state." During the museum session, children will figure out where these definitions came from and how the Ural city amazed its contemporaries. The introduction to the 19th century is structured in a quest format. Instead of a sequential narrative, participants will search for clues, compare facts, and carefully examine items in the permanent exhibition. Thus, trade, industry, and urban life cease to be just a collection of dates: each answer helps restore another piece of the historical picture. One of the topics is related to coin production. Kids will learn why money was minted in Yekaterinburg and what role this enterprise played in the life of the city. Another storyline is dedicated to factories and the processing of Ural gemstones. The stones that the region was famous for were turned into intricate products and connected local craftsmen with clients far beyond the Urals.
