I spent some time exploring Amesbury, the nearest town to Stonehenge, searching for Sarsen stones used in old buildings. We are always told that the missing Sarsens of Stonehenge were broken up for building or hardcore. I have not found any Sarsens used on the farms around Stonehenge as they are in the Pewsey Vale and on the Marlborough Downs.

Hair By Joanna is in The Old Post Office which is reputed to have a Bluestone slab. I presume it is the large stone threshold which is blueish. It isn't a "Bluestone" though, just a type of slate I think.
The Antrobus Arms is said to have four Sarsen steps. (Click any photo to expand it)
No, not Sarsen.
There are many walls in Amesbury made of odd stones and flints. Much of the Church is as well.
I've looked all round the Church's sure foundations, I have scoured the walls on roads and carparks, I can't spot any Sarsen.
If the Sarsens of Stonehenge were broken up for building stone then the stones are well hidden. If you know for any please tell me. And if the broken stones are not to be found it supports the idea that maybe the missing stones never were there and the circle was never completed.
