Still standing and still in everyday use - the arched wooden bridges built in China nearly 1,000 years ago demonstrate the true skill of the master craftsmen who first constructed them.
These stunning structures show how not every part of China has been altered by its remarkable rate of development.
The bridges, suspended between two banks of lush greenery and built from the wood of the trees surrounding them, are still a fully functional part of life in the Fuijan and Zhejiang provinces along China's south east coast.
Still in use: A man walks across the Yangmeizhou timber arch lounge bridge, in the Kengdi village of Shouning County, which was built during the Ming Dynasty.
Idyllic: The Luanfeng Bridge, a timber arch lounge bridge, in the Xiadang village in south east China.
