On the northern tip of the Bohai Coast, Shanhaiguan is the end of the road for the Great Wall. After 8,850 km (5,500 miles), the massive structure plunges into the sea. During the Ming Dynasty, Shanhaiguan was fortified to prevent hordes of mounted Manchurian warriors from pushing to the south. Now local tourists swarm the town during the summer. An impressive wall still surrounds what was the Old Town, sadly razed in 2007
and rebuilt as a spiritless faux-historic tourist area.
