Trilithon
From Wikipedia, the free encyclopedia
A trilithon (or trilith) is a structure consisting of two large vertical stones (posts) supporting a third stone set horizontally across the top (lintel). Commonly used in the context of megalithic monuments. The most famous trilithons are those at Stonehenge and those found in the prehistoric temples in Malta, which are a UNESCO World Heritage Site.
The word trilithon is derived from the Greek 'having three stones' (Tri - three, lithos - stone) and was first used by William Stukeley.
The term also describes the groups of three stones in the Hunebed tombs of the Netherlands and the three massive stones forming part of the wall of the Roman Temple of Jupiter at Baalbek, Lebanon. Far from Europe and the Middle East, another famous trilithon is the Haʻamonga ʻa Maui in Tonga, Polynesia.
