Description:
Stonehenge, Salisbury Plain, England. The ‘cornerstone’ of Stonehenge refers to the foundation stone or keystone of the monument. This sarsen stone, strategically positioned, marks the site's main astronomical alignment with the sunrise on the summer solstice. It is the geometric and symbolic reference point for the entire architectural complex, demonstrating the technical and cosmological mastery of the Neolithic builders.
Stonehenge is a megalithic monument located on Salisbury Plain in England. This circle of standing stones was erected between 3100 and 1600 BC in several phases of construction. The site reveals a complex architecture with massive trilithons and a precise astronomical layout. Listed as a UNESCO World Heritage Site in 1986, Stonehenge remains one of the most enigmatic prehistoric monuments in the world. Its exact use remains debated: solar temple, astronomical observatory or burial site. This technical feat bears witness to the expertise of Neolithic populations and the British Bronze Age.
