This large stone tunnel has been carefully cut out of the rock beneath

the city. Its surfaces are completely coated in a thick layer of ice,

but what created this intense cold is not apparent. Icicles hang from

the ceiling like frigid teeth, and the floor is covered with powdery

snow-like ice shavings. The tunnel forks here, a much larger branch

continuing to the south, and two smaller ones to the west and

northeast.
