Introduction to the Temple of Venus: Located in front of the Temple of Baccas, it is a circular building built in 245 AD. The temple is small and exquisite, with graceful stone pillars and quiet winding paths in the courtyard. There is an ancient quarry on the road leading to Beirut. There is a stone there that is called "the largest building stone in the world." The stone is 21.5 meters long, 4.2 meters high, 4.8 meters thick, and weighs about 2,000 tons. It was originally intended to be used to build a temple.
