A group of three horizontally lying giant stones which form part of the podium of the Roman Jupiter temple of Baalbek, Lebanon, go by the name "trilithon", although they do not fit the above definition. The location of the megalithic structures is atop of a hill in the region, known as Tel Baalbek. Numerous archaeological expeditions have gone to the site starting in the 19th century, primarily German and French groups, and into the 20th century research continued.[1] Each one of these stones is 70 feet long, 14 feet high, 10 feet thick, and weigh around 800 tons. The supporting stone layer beneath features a number of stones which are still in the order of 350 tons and 35 feet wide.[2] In the quarry nearby, two Roman building blocks, which were intended for the same podium, even surpass 1,000 tons, lying there unused since their extraction in ancient times.
