Fodor's Expert Review Military Museum of the Chinese People's Revolutions
Closed for major renovations, this museum is scheduled to reopen in 2015. Stuffed with everything from AK-47s to captured tanks to missile launchers, this is a must-see for military buffs. Five thousand years of Chinese military history are on display, and kids especially love every minute of it. It's easily accessible by taking a 10-minute subway ride west from Tiananmen Square.
