Stonehenge was built by the prehistoric Neolithic civilization in Britain, whose exact cultural and societal characteristics remain enigmatic. Construction began around 3000 BCE and continued into the late Neolithic period, with monumental structures made of massive stones and earthworks. While the purpose of Stonehenge is still debated, it is commonly believed to have served as a ceremonial site or astronomical observatory. The alignment of the stones with celestial events, such as the summer solstice, suggests it had significant spiritual or religious functions. The skill and effort involved in its construction reflect the societal organization and advanced capabilities of its builders.
