Xi’an City Wall, Xi’an, Shaanxi Province, China

Xi’an City Wall, represents one of the oldest, largest and best preserved Chinese city walls. It was built under the rule of the Hongwu Emperor Zhu Yuanzhang as a military defense system. It has been refurbished many times since it was built in the 14th century and as recently as 1983. The wall encloses an area of about 14 square kilometres (5.4 sq mi) and tourists can rent bikes to ride along the wall.  We had fun riding the tandem bike for awhile, but did not make it all the way around as it got too cold.  We drew some attention from locals that wanted to take pictures with the girls and grandma and grandpa!
