About this photo
The fortifications of Xi'an were built in the 14th century to protect this once imperial city. It is the oldest and largest of China's city walls. The 14km (9 miles) of bricks surrounds an area of 14 sq km (5.4 sq miles) in Xi'an's centre. Wider than it is tall – the base spreads across roughly 15 metres tapering to 12 metres at the top and stands at 12 metres tall – you can walk or cycle around the perimeter, looking down on the ancient city which lies at one end of the old Silk Road trade route.
