Has there ever been an attempt to put the Stonehenge back together?

Yes there have been a number of re-construction attempts on various sites. There is considerable doubt as to what the original structure, built by the Druids, was intended for, it has been suggested it was an astronomical computer for computing surise-sunset, possibily eclipses and so on, in connection with religious rites, as one might guess. Priestly science was also a big deal in ancient Egypt, who also practiced Sun Worship ( as did almost all ancient cultures except the Nordic , there was no solar deity in the Norse Pantheon, and Hamilton remarks on this.l Stonehenge reconstructions stress a sort of rotunda structure with columns in a circle, some connecting devices (possibly trusses) but no real roof. It may well have been a primitiv e observatory, it is no easy task to try to reconstruct something like this, and there is considrable latitude for artistic license. there is a good one (Stonehenge reproduction) In Washington state. I have seen pictures of it. Yes there have been a number of re-construction attempts on various sites.
