And, as I pointed out on that "other" thread, with regard to Alexander destroying the city, and putting it under water, well in AD 502 an earthquake hit the entire region, from Beirut to Akko, and this is when the parts of Tyre that are below sea level fell. Not by ANY nations. It rebuilt itself after that as well. In the byzantine time it went through its second golden era
