10Xuankong Si – China

Out of five Sacred mountains in China, Mt. Heng (Heng shan) is one of them. It is located in Shanxi province. this fabulous state of the art locality was built in 491 AD. The art of Engg. that was used at that time is still offers a lots of attraction to modern engineers.

It may be the first recorded instance of deliberate over engineering.The depth of the holes and the hardness of the rock provided a strong base. There are sufficient supports to ensure that if the crossbeams ever need to be replaced then one can be removed at a time without impacting on the structural integrity of the monastery.
