Mapledurham Mill by the Thames.
Rather unexpectedly we had some free time on Sunday so, as Simon and I a big fans of going on random adventures and it was a lovely day, we went to visit this working mill which is not too far from Oxford...

Yes it is all very picturesque BUT it is not just any old mill because, as well as being the last working mill on the Thames, it is also famous for being on the cover of this album:
Black Sabbath by Black Sabbath 1970
:)
(I bought some flour from them while I was there. It is not all rock tourism! I got some wholemeal and some semolina.)
A short walk from the Mill is also Mapledurham House, we had a look about inside. It is one of those stately homes where the family still live there but open it up to visitors on weekends in the afternoon.
This is the view from their front door.
All-in-all a fun random adventure :)
