Scuba Diving Beneath Hagia Sophia

BLDGBLOG reports on an upcoming film that nearly makes me wet my pants with excitement:

While scuba diving beneath Hagia Sophia, an exploratory team led by filmmaker Goksel Gülensoy has "managed to reach areas that until now, no one had ever managed to reach," down there in flooded basins 1000 feet beneath Istanbul's heavily touristed religious structure.
In the process, they have discovered 800-year old submerged graves containing the remains of "canonized children."
This was just part of a larger, underwater archaeo-spatial survey:

The divers and specialists explored the connection of the basins underneath Aghia Sophia with the aqueduct and the palace of Top Kapi. In addition they attempted to locate the secret tunnels from Tekfour Palace to the Islands.

Those "secret tunnels" are presumably the rumored subterranean extensions of the Anemas Dungeons – but who knows.
