Cradled in the folds of the Himalayas, Bhutan has relied on its geographical isolation to protect itself from outside cultural influences. A sparsely populated country bordered by India to the south, and China to the north, Bhutan has long maintained a policy of strict isolationism, both culturally and economically, with the goal of preserving its cultural heritage and independence. Only in the last decades of the 20th century were foreigners allowed to visit the country, and only then in limited numbers. In this way, Bhutan has successfully preserved many aspects of its culture, which dates directly back to the mid-17th century.
