These examples, closest to the Abbey, are the easiest to see: they stretch away into the distant undergrowth and become more overgrown the further you go. There is a stretch of about a quarter of a mile of Dragon's Teeth on the riverbank. The iron hooks that can just be seen on the tops of some of the pyramids were for hanging thick cables across the stream to impede the progress of tanks up the river. Any German engineers trying to cut these would have been shot at by a further pillbox on the far side of the river. 

At this point, only the tops of the pyramids are visible.

Hidden in the undergrowth on the far side of the river are a further set of Dragon's Teeth. This bank is very steep, and to the South, from where the Germans would have approached, so these obstacles would have been a formidable obstacle to tanks: probably an ambush point.

The remains of the Monk's sleeping accommodation from the Cistercian Abbey are in the background of these shots, showing how close the obstacles are. The Army demolished many historic walls to provide for a clear field of fire: so the ruins are even more depleted than Henry VIII and Thomas Cromwell intended!

Two pillboxes also survive in nearby farmland. These were an integral part of the defensive position established here at Waverley. There was a ditch running between these and the riverbank, long since filled in. It can still be seen from aerial photographs, however. 

These Dragon's Teeth have been removed from their original site and placed by the path that leads to the Abbey, which can be seen in the distance in the right-hand photo.
