New Stonehenge theory

There is a new theory concerning the function of stonehenge:

The megaliths would not have been used for ceremonies at ground level, but would instead have supported a circular wooden platform on which ceremonies were performed to the rotating heavens, the theory suggests.

Sounds interesting and not entirely implausible (at least to a non-archaeologist like myself).  (Full article here.)

After all these years, I still find thinking about stonehenge strangely magical...
