the great wall was renovated from time to time after the qin dynasty. a major renovation started with the founding of the ming dynasty in 1368, and took 200 years to complete. the wall we see today is almost exactly the result of this effort. with a total length of over 6,000 kilometers, it extends to the jiayu pass in gansu province in the west and to the mouth of the yalu river in liaoning province in the east. what lies north of beijing is but a small section of it.
