Baalbek, Lebanon

Baalbek

Pearl of the ruins of the once thriving city – temple ensemble in antique style. Only here the Romans did not have the technology to install the stone blocks weighing up to 1 000 tonnes (these are at the bottom). For comparison: the Athenian Parthenon less Lebanese giant twice, and the largest block of Cheops pyramid weighs “only” 90 tons. Credited with creating the foundation is credited to the Egyptians, if not giants. And some believe that it could be the base of the Tower of Babel.
