Dragon Gate, Kunming
This spectacular complex of grottoes, pavilions, stone ladders, steps, and twisting tunnels was hollowed out of the rock, beginning in 1781, by a Daoist monk named Wu Laiqing. The work was continued after his death by local villagers and pious gentlemen, and completed in 1853. The cliff-hugging pavilion seen here is classic, resembling those from paintings of a thousand years earlier.
Note: don't confuse the Dragon Gate in Kunming with the Dragon Gate in Loyang.
