Cosmic cromlechs, ancient stone monuments often arranged in circular formations, have fascinated historians and archaeologists for centuries. These outdoor sculptures, believed to have astronomical and ceremonial significance, are found across the globe. Among the most famous is Stonehenge in England, a UNESCO World Heritage Site renowned for its alignment with solstices. Another notable example is the Callanish Stones in Scotland, which form a cross-shaped pattern linked to lunar cycles. In Brittany, France, the Carnac Stones feature over 3,000 standing stones arranged in rows, possibly marking celestial events. These cosmic cromlechs not only showcase prehistoric engineering but also reflect humanity's enduring connection to the cosmos. Their mysterious origins and purpose continue to inspire awe and scholarly debate.
