NOT ALADDIN'S CAVE, but still not bad:

Discovery of giant underground quarry in Jordan Valley may rock archaeological thinking
By Ran Shapira (Haaretz)

A spectacular underground quarry has recently been discovered in the Jordan Valley north of Jericho, which archaeologists believe may have marked a biblical site sacred to ancient Christians.

The large cave was discovered by Prof. Adam Zertal and a team from the University of Haifa which has been conducting a survey of the region since 1978. "When we reached the entrance to the cave, two Bedouin approached us and warned us not to go in, because it was cursed and inhabited by wolves and hyenas," Zertal said yesterday from the site.

They entered anyway, discovering a ceiling supported by 22 gigantic columns on which various symbols were carved, including 31 crosses, a possible wheel of the Zodiac and a Roman legionary symbol. The columns also had niches for the placement of oil lamps and holes that apparently served as hitching posts.

Zertal says their working theory is that the site is Galgala, biblical Gilgal, mentioned on the sixth-century Madaba mosaic map. The cave, buried 10 meters underground, is about 100 meters long, 40 meters wide and 4 meters high, is the largest artificial cave so far discovered in Israel.

Pottery fragments and the incised symbols point to first usage at the beginning of the Common Era, but the cave appears to have been used for some centuries.
