This sprawling exhibition site was once host to a complex of exhibitions showing off the economic and technological fruits of the Soviet world. Nowadays the 68 pavilions are full of pretty ramshackle stores with all sorts of household goods. The center boasts some 40,000 square meters of outdoor space and nearly 130,000 square meters of indoor exhibition space. It hosts some 350 exhibitions each year and 40 to 50 of them are international. The annual visitor influx is close to 10 million. Admission is free.
