BhutanThe Kingdom of Bhutan is one of the most mysterious and least studied countries in the world. Isolation from the outside world has been achieved thanks to its geographical location — Bhutan is safely hidden away from modern civilization. Although not all of the population of Bhutan speaks the official language, today it is compulsory to study it in all schools in the kingdom. But despite all the benefits of civilization, Bhutan remains one of the most closed countries in the world. In central Bhutan, the air temperature reaches 26 degrees Celsius in summer and can drop to -16 in winter.
