By boat and then by oxen.
"To get the rock from that Welsh site to Stonehenge it is likely that the rock was brought down to the sea, put into boats, and then brought by water
to a nearby river, and then brought up the river perhaps as close as two miles to the site, although depending on the way they went, it may be as fas
as some twenty-four miles.
An experiment was carried out not too long ago, which showed that it takes about fifteen people to haul a ton of rock on the ground, but it becomes
very, very easy to move that load by boat. It may have been considerably easier than anticipated to haul the rock, and when it is also recognized that
domesticated oxen were available at the time to act as beasts of burden (their shoulderblades were used as shovels) then the somewhat dramatic
pictures of hundreds of sweating natives hauling rock over the hillside become perhaps a little fanciful. "
