Although there are lots of debates over when the standing stones were assembled, it is fairly safe to say that this happened at some point during a 1000 (or so) year period centred on about 3000 BC.
Despite current beliefs (based mainly on Victorian mistakes) it is more likely that Stonehenge was used for mid-winter rituals than mid-summer ones.
