What was Stonehenge actually used for?

The answer

Built in stages between roughly 3000 and 2000 BCE on Salisbury Plain in England, Stonehenge's exact purpose remains debated. Its alignment with the summer solstice sunrise and winter solstice sunset strongly suggests astronomical and ceremonial significance. Recent discoveries of cremated remains indicate it also served as a burial ground, and the bluestones were transported over 240 kilometers from Wales - an immense effort suggesting profound ritual importance to Neolithic peoples.
