The ancient civilization known for the construction of monumental stone structures, including Stonehenge, is the Neolithic culture of Britain. This civilization, which thrived around 3000–2000 BCE, is known primarily for its distinctive megalithic architecture. Stonehenge, located in Wiltshire, England, is a UNESCO World Heritage Site and symbolizes the ingenuity and ceremonial practices of these early societies. The exact purpose of the site remains a mystery, but theories suggest it may have been used for astronomical observations, religious rituals, or as a burial site. The construction of these stone structures reflects their advanced organizational skills and cultural significance.
