Windmill Hill

Today's excursion was to Burton Dassett Country Park, in nearby Warwickshire.  It was cold, windy, and occasionally showery, but we braved the weather and walked up the hill to the mystery building.  According to the information boards, there was a windmill on this hill, but further down the slope.  The building at the very top is a mystery, as no one knows what it was used for.
