Plas Brondanw Gardens, north Wales, part of the estate owned by Clough William-Ellis. Apparently the tower - known as Folly Castle (which it is) - was a wedding present from William-Ellis' fellow officers. Nice. He was. also the creator of Portmerion (for any fans of the old TV series The Prisoner)
Wonderful shot - mystical! And I'm still a big fan of that old TV show! I think it was beyond its time. Patrick McGoohan is a favorite and did some great TV shows and movies. I loved the bubble that came out of the water and chased him down with every escape attempt.
