Xi’an City Citadel

A feature of the old city of Xi’an are the immense walls that protect the old city precinct. The sheer height and width of these walls are extraordinary.
Atop the wall it is possible to ride bikes and it would be approx 25 metres across and I would estimate about 50-60 metres high which made the city very difficult to attack.
There were also beautiful gardens in and around the wall.もっと詳しく
