Sadly the Bronze age Airlie Souterrain partially collapsed last year due to continued agricultural ground works. After having survived relatively intact for over 2,000 years some of the stone roof slab fractured and collapsed and is now no longer safe to visit. The first few metres from the entrance are still accessible but with caution.
This is one of the reasons that the capturing and digital preservation of these heritage sites is such a passion and significant from a wider anthropological perspective.
It is a site I have spent much time in over the years and communing with the atmosphere and the relatively anechoic acoustics of the space is a place to internalise. I have theorised that this particular Pictish souterrain being different in many ways from the other 200 or sound found around North East Scotland and the Highlands may have been a space for inward reflection and communing with the ancestors. The serpent stone carving on one of roof slabs at the midway point may not be a serpent after all: it may be a Bronze Age sound wave looking like a sine wave!?
