The town wall's east gate, which the Great Wall once linked up with on its way from the mountains down to the sea, has been tarted up for tourism. This was Shānhǎiguān's principal watchtower – two storeys with double eaves and 68 arrow-slit windows – and is a towering 13.7m high.
Several other watchtowers can also be seen and a wèngchéng (enceinte) extends out east from the wall. You can walk along a small stretch of the wall here.
