This reminds me a lot of Mayburgh henge, it’s in a similar state of disrepair and has the same air of abandonment. The entrances are still well defined but the bank is badly damaged and the internal ditch has just about gone. Apparently it is thought that the banks of this henge and its two siblings were covered in gypsum crystals, echoing the chalk earthworks of the south of England. The henge also stands over an earlier mile long cursus which ran in a northeast to southwest direction and later more than 2 dozen round barrows were constructed in this area, so it was obviously an important place for some considerable length of time.
