What have archaeologists already discovered about Stonehenge?
Archaeologists have discovered many pieces of information about Stonehenge, although the most interesting questions of why it was built and what it represented to its builders, cannot be answered conclusively absent written records, which, since the monument predates writing in this period in Britain, will never surface, and thus those questions will remain unanswered.
Archaeologists have used radio-carbon dating to discover that some European megaliths date to 4500 BC. They have unearthed a wooden structure predating the existing stones, and through radiocarbon and tree ring dating, placed that ur-Stonehenge at ca. 3000 BC. The standing stones have been dated to 2100-1500 BC. They have also found the “Aubrey holes”, filled with chalk, some containing human cremations .
