'ere ye go guv      nope.  the burials are buildings that are shaped of a huge slab, like the type you pour cement on the ground to make a solid foundation, but with underground/parallel chambers and other dug-outs. at best, with an additional smaller slab to look like a pseudo-temple.  say what you want, believe what you want, but don't perpetuate the lie that it was a tomb, nor a pathetic water pump/cistern.
