There are several parts of Bet Guvrin which I found fascinating. First, it is one of the only places in Israel where the public can participate in an archaeological dig. There are numerous caverns which were dug under the houses of people in the area which were later used for garbage. Because the artifacts in the garbage were mixed, there are no formal strata that need to be preserved, so they are willing the let the public help out in digging.

Also, all of the caverns were dug by hand and many of them are enormous. They were dug over centuries by just extending the floor of the cavern further down. It is a popular attraction for Israelis but few foreigners bother to visit.
