A journey under Malta

Professor Hex links to this article on the Hypogeum in Malta, a subterranean burial chamber so large that people got lost and never returned. One teacher and her class of 30 never returned. Well, that's what this article claims anyway. Here's a snippet of some of the far out claims:
She claims that out of this lower tunnel on the far side of the chasm emerged, in single file, several very large creatures of humanoid form but completely covered with hair from head to foot. Noticing her, they raised their arms in her direction, palms out, at which point a violent "wind" began to blow through the cavern, snuffing out her candle. Then, some “thing” wet and slippery (apparently a creature of a different sort) brushed past her.
It's fascinating stuff, whether true or not.
You can see pictures of parts of the Hypogeum here. Here's an article that treats it more soberly as a tourist attraction:
For about a 1,000-year span, the Hypogeum served as a necropolis, a city of the dead that eventually housed the remains of about 7,000 people. It was one of many megalithic structures strewn across Malta, built by a complex Neolithic culture that mysteriously disappeared around 2500 BC.
Even without slimy things and hairy humanoids, the Hypogeum is interesting as an underground Stonehenge and home of a death cult of some kind. Thanks Hex!
