Beijing’s city wall was built around 1435. It stretched for 23.5km with one part running where Metro Line Two is now (inner city wall) and one part running where the southern part of Ring Road Two is now. Since 1949 (and especially around 1965), most was torn down to make room for Ring Road Two, Metro Line Two and Tiananmen. Now only 1.5km remains behind Beijing Station. It has recently been restored and surrounded by a small park. The wall also houses a cafe and a gallery.
