Dengfeng sights

The Historic Monuments of Dengfeng, China, were added to the UNESCO World Heritage List in August 2010, and now — to protect the buildings from damage caused by excess carbon dioxide, incense smoke and humidity levels — the government plans to restrict the number of tourists during peak travel times, according to China Daily.

The cluster of 11 monuments in the Songshan Mountains includes the Shaolin Monastery, Three Han Que Gates and the Observatory.
