A Beijing Must See!!
The Temple of Heaven is a Beijing must see. This is a fairly long rectangular park that includes many excellent features and structures. The Echo Wall is a circular structure in which your sounds travel around the inside wall to be heard on the other side. The actual main temple is very beautiful and impressive, as are the halls on either side of it displaying religious artifacts.
There are many gates to pass through with smaller temples, sacrificial alters, and parade grounds. The park that surrounds the temple structures is also a good place to watch the locals or relax with a snack.
