At the Syriac monastery of Deir-ul-Zaferan (just outside Mardin, in Turkish Kurdistan) there is a basement room that was once a pagan solar temple - there's a small window in one side that lights up an altar across the other side at dawn in midsummer. I think it's about 2500 years old.
The mindboggling thing about it is the ceiling. The room is about
50 by 30 feet, and the ceiling is dead flat *stone blocks*. No transverse beams, arches or any discernible support. Somehow or other the interlocking arrangement of those blocks holds hundreds of tons of rock absolutely stable above your head.How on earth was it done? I've seen nothing like it anywhere else from any period. You can't see anything from above, as the mediaeval monastery structures get in the way.
