Watermill

I took my camera with me yesterday when we went out, but it was teeming with rain and I wasn't driving so blip opportunities passed me by. I had no inspiration for another indoor blip so i missed a day - tut, tut! Out again today, and again today it was pouring with rain. However I was driving today and able to stop to get this quick blip. I have passed this former water mill on the outskirts of Dorking very many times. It intrigues me because there doesn't seem to be any water thereabouts, so I studied the local map and find that it is situated on the Pipp Brook, a small stream that runs into the River Mole nearby. i wonder how many years since it was a working mill.
