Housed in a beautiful 19th century building, once belonging to a prominent local merchant family. True to its name, this museum has a huge collection of rocks and minerals – some even some from outer space, like a few moon fragments brought home to Earth by automatic probes and one of the world's largest iron meteorites which crashed into the Sikhot-Ailin mountains in the forties. If you are not into stones, you could check out the small section on tools and equipment related to prospecting in the region or the collection of prehistoric plant and animal fossils. Outside the museum there are a few large monoliths of minerals, ores and rocks.
