Simatai Great Wall
It lies 120kilometers (44.7miles) from downtown Beijing. The section is 19kilometers (11.miles) long with 35 magnificent watch towers. Wangjinglou(watching the capital tower) is located at a vantage-point, nearly 1,000 meters(3,280 feet) above the sea level. It is so called because, standing at this tower on a clear night, one can see the lights in Beijing.
