Fallen sentry

One of the Dragons Teeth, World War Two anti tack obstacles, out of a line blocking a gully coming of Studland Beach has become dislodged and fallen on the obstacle below. I was surprised to see how flimsily these huge concrete blocks were secured to the ground; it would appear that beyond being sunken a few centimetres below the surface, all that held the concrete blocks in place where 2 crossed iron bars secured in the ground, around which the concrete had been poured.  It shouldn't really come as that much of a surprise, as the period of their construction was one of turmoil and limited resources; defences conceived and deployed in hast, in a make do and mend culture.  Looking at some of the other obstacles in the line, I fear more will follow if some restorative work is not carried out.
