... Orthodox scholars of today scoff at all suggestions that Romans had not brought the great blocks to the temple site, despite the fact that building with megalithic blocks was not at all in the Roman style, and was no longer practised in those days.Romans knew and used concrete. The Colosseum still standing in Rome is a good example of a classic Roman concrete structure.

The sad truth is that regarding the Trilithon, some scholars have mental blocks its own size. Admissions that blocks weighing over a 1000 metric tons were quarried and transported in prehistoric times would invite uncomfortable questions on what technology had made it all possible. Regardless of such touchy issues, I have several personal observations, which support dating of Baalbek's megalithic walls to the megalithic era. Have a look at this nice northwestern view of the wall as it was circa 1870.
