I am one of the people who visited as a tourist before heading off somewhere else. (Dead Sea, Massada & Beersheba) on a long day trip from Tel Aviv in late 1978. I had a guidebook, pre Lonely Planet and a Guide, Israeli who gave us a short, about 15 min tour. A couple of signs, noting to show that it had been there about 8000 years. I remember it as a dilapidated version of Troy, only a whole series of foundations and only to be seen with a guide who knew what he was talking about. Thankfully he did, a quick intro about Joshua before mentioning that the tale was dubious, the layer destroyed by an earthquake was hundreds of years before him. He then described the visible layers then we were on our way again. It needed interpretation boards and restoration. It does not look as though anything has happened apart from banning Israeli tourists. As Palestine's oldest site it needed a WHS designation.
