2. The Treasury, Petra, Jordan
Some of the mystique of Petra comes from the dramatic nature of its entrance. This is the Siq; a narrow canyon that winds for more than a kilometre through sheer sandstone walls to burst into a small sun-drenched clearing with the Treasury, or Al Khazneh, directly in front.
"It seems no work of man's creative hand, By labour wrought as wavering fancy planned; But from the rock as if by magic grown, Eternal, silent, beautiful, alone!" - Dean Burgon "Petra"
