Overview

• Seahenge and its sister structure, Holme II, were constructed around 2049 BCE during a period of severe climatic deterioration.
• The monuments feature an upturned tree root and split oak trunks, aligned with the summer solstice sunrise.
• Researcher David Nance theorizes that the structures were meant to extend summer by 'capturing' the cuckoo, a symbol of fertility.
• Holme II might have served as a site for ritual sacrifices to ensure cosmic harmony and agricultural fertility.
• Both structures reflect early societies' attempts to mitigate the impacts of prolonged harsh winters and climate instability.
