Mustang, a kingdom whose existence has long been kept secret, is in the territory of Nepal in the fabled land of Lo. It is hidden behind the high wall of the Himalayas, like a wedge driven into Tibet. The afternoon wind blows everyday, tirelessly obliterating all trace of each caravan. In front of the royal palace, monks intone ancient Buddhist prayers over and over again. Time seems to have stopped in this medieval fortress. Electricity, roads and cars are unknown to these people and yet, in some ways, they are ahead of us: in their incredible knowledge of nature and in their way of life. The fortress of Lo Mantang continues, however, to guard its secrets.
