Stonehenge was constructed first. The construction of Stonehenge began around 3000 BC and continued in phases until around 1600 BC. The Moai statues of Easter Island, on the other hand, are believed to have been carved between 1400 and 1650 AD. While both are ancient sites of significant historical and cultural importance, Stonehenge's construction predates that of the Moai statues by several millennia.
