In addition to the locations for viewing the Great Wall north of Beijing, many other parts of the Wall can be visited as well. The portal in the far west, called Jiayuguan, is known as the 'greatest pass under heaven' and is well worth visiting. The one in the east, at Shanhaiguan or 'Mountain-Ocean-Pass', is of tremendous significance in Chinese history. All of these are open to visitors and have historical objects on display.
