The people who populate the southern slopes of the east Khasi hills are generally called the War-Khasis. They were amongst the first to notice the properties of the Rubber fig. As there was a huge need for bridges to traverse amongst the different hill spaces in the Cherrapunji and Mawlynnong valley systems, they began the growing of the bridges with the help of available resources.
The Living Root bridge in Mawlynnong between Riwai village and Nohwet village, is made by a great engineer from Nohwet village. His name is Shri Nongmuna Khongthohrem from a hundred years ago. Comment by Henry Khongthohrem in Timothy Allen, (2011). Living Root Bridges - Timothy Allen.
