The caption under a photo of the obelisk reads, "Brightling Needle, one of "Mad Jack" Fuller's famous follies. It stands some 940 feet above sea level in a lovely East Sussex countryside". The article goes on the say that Sussex feared invasion by Napoleon and, "Indeed so imminent was the danger in 1805 that, on the hill behind us, some 640 ft above the level of the sea, a beacon was made ready to give alarm should enemy ships be sighted". Brightling Down or Brightling Beacon is approximately 646 ft above sea level and the oblelisk or Brightling Needle is about 65 ft tall. So the height of 940 feet mentioned in the photo caption is clearly an error.
