Baal-Bek

An ancient construction in Modern Lebanon measuring 5,000000 square foot that was somehow built by a very advanced culture with monolithic blocks weighing well over 1200 tons. The later master builders, the Romans, built a massive temple on top 1500 miles from their Empire centre, as they thought their god Jupiter must have originally built this as it was seen to be far beyond the work of mere men. Was this a very ancient spaceport?
