Whilst cycling back to Oxford after researching my Church Micro in the village, I happened upon this water feature, sadly I've been unable to find any information about it online, although I must admit I was somewhat at a loss, as to which search terms to use.
Parking is available at the top of the hill on Jarn Way, for multiple cars, or there's space for one at the bottom of the hill, on Sandy Lane, where the footpath starts.
