Anyone who has walked along the path through Bee Wood below Froggatt Edge must have momentarily paused at the strange tomb like structures on the edge of the path and wondered what they were.  I certainly have done, and unable to find any information about them in my Peak District books or on the internet, I contacted the National Trust who manage the woodland, and I am delighted to report that I now have the answer!

Apparently they are part of a water company piping system along the path which is known locally as the ‘pipe track’.  The rectangular gritstone structures cover vent and access holes to the ‘cut and cover’ pipe.  The pipe was apparently a dug ditch that was covered in an arch of bricks then covered back over.
