The Trilithon is composed of three stones each measuring 19 metres long x 4.2 metres wide x 3.6 metres broad. Hewn from natural crystalline limestone with a specific gravity of about 2.7, from a quarry 1 km mile away, they weigh 870 tons each.
They have been raised to a height of 10 metres and have been so accurately cut and placed that a razor's edge cannot be placed between them.
They have been laid upon a layer of 19 similar blocks weighing between 350 and 400 tons each.
Quite an impressive feat of engineering - the Baalbek foundation stones shown above are the largest pieces of hewn rock on the face of the Earth.
At the link below it is argued that the foundation stones are far older than previously thought and that Roman architects just simply added to an already existing structure.
The collosal stones (each weighing 800 tonnes) are situated in a wall of the great acropolis of Baalbek in Lebanon and it is said that:
"..they are so accurately placed in position and so carefully joined, that it is almost impossible to insert a needle between them.."
