The achievements of science and technology, including an awesome collection of early-20th-century Russian cars, fill an entire Moscow block. The monumental building that houses the museum was built in 1875 by Ippolit Monigetti, a Russian of Italian birth whose day job was designing annexes on the royal family's country estates. The endless series of exhibits—miners' lamps, Soviet televisions, even a full-scale replica of the USSR's first atomic bomb—can be overwhelming
and esoteric, but kids love it. There are also many good temporary exhibits, as well as the movie museum (mostly Soviet animation films) and a small planetarium at the southern entrance.
