A henge is a prehistoric monument characterized by a circular area enclosed by a bank and a ditch. Often, these structures feature standing stones or wooden posts arranged in a circular pattern. The most famous example is Stonehenge, located in England, which dates back to around 2500 BCE. Henges are believed to have served various purposes, including ceremonial, astronomical, and social functions. Henges are typically associated with the Neolithic and Bronze Age periods in Europe. They vary in size and complexity, with some containing additional features like burial mounds or alignments to celestial events. Archaeologists study henges to gain insights into the cultures and practices of ancient societies.
