The passage calls its largest chamber a “splendid hall,” about 50 feet broad and 70 feet long.

Smaller caverns branch from the larger chambers in different directions, extending the underground route.

The passage says a subterranean lake lies about two leagues from the entrance, a period estimate of distance.

Visitors observed stalactites by torchlight, whose reflected flames made them appear like thousands of brilliant gems.
