My father and I went to Avebury after seeng Stonehenge on the advice of some English pilot friends (the main aircraft testing faciliy for the RAF is near Salisbury) and it was incredible. Stonehange was awe-inspiring for the construction (massive slabs of stone balance atop other massive slaps of stone) but the sheer cope of Avebury, plus that fact that you could walk right up to the stones and *touch* them, was amazing.

And it amused both of us immensely that the medieval church in Avebury is built such that the high alter of the church is located exactly where the altar of the original stone circle would have been.
