Meghalaya, North India, where villagers have come up with a unique construction technique that harnesses nature in its purest form – they grow their own living bridges! Using the roots of the rubber fig tree, the natives have created an amazingly elaborate network living bridges, some of which, both researchers and natives believe, are over 500 years old! These extraordinary examples of living architecture are also lessons in patience, since they take about 15 years to grow, and are often continued by the sons and daughters of the original builders. With age, though, the living root bridges grow stronger and can often support the weight of 50 or more people at a time!
