The word trilithon is derived from Greek 'having three stones' (τρι- tri- 'three' + λίθος líthos 'stone') and was first used in its modern archaeological sense by William Stukeley.
Other famous trilithons include those found in the Megalithic temples of Malta (which like Stonehenge are a UNESCO World Heritage Site), the Osireion in Egypt, and the Haʻamonga ʻa Maui in Tonga, Polynesia. The term is also used to describe the groups of three stones in the Hunebed tombs of the Netherlands.
