In the barren landscape of remote western Tibet lies the ruins of a mysterious kingdom. A kingdom whose capital was 3600 meters high on the Tibetan plateau. A kingdom that offers archaeological treasures that compare with Italy’s Pompeii. Once controlling the trade in gold, silk and spices between India and China, it was a kingdom of fabulous wealth and great religious significance. For two centuries it was the cradle of Himalayan Buddhism. Yet this spiritual and commercial hub, which prospered for seven centuries, vanished without a trace in 1630. Until now the mystery of what was the Tibetan kingdom of Guge has remained unresolved.
