The Drum Tower was built in 1272 and moved to a new location in 1800. The Bell Tower was built around 1700. Originally, the towers were used to play music and later on to tell Beijingers the time. Now they house a 63-ton ancient copper bell and a number of ancient/replica drums. Free guides start tours at specific times, and the Drum Tower also has performances every hour or so (usually around half-past). There are great views from the top of the towers, but be prepared to hike up the 60+ (very steep!) steps. Ignore the touts at the bottom who try to push off hutong tours in rickety tri-shaws.
