Special conditions

Why do we find such incredibly well-preserved objects from 2000 years ago at Vindolanda?

The Roman builders covered the foundations of the previous forts with clay, turf, bracken and heather, sealing the ground below and thus creating anaerobic conditions. These conditions fortunately preserved many rare metal and wooden objects, as well as leather and textiles.

Anaerobic conditions are a result of the ground being waterlogged, due to the rising water table at Vindolanda. The objects are almost entirely deprived of oxygen, and there is very little bacterial activity which would normally destroy such buried objects.

Listen to Dr Andrew Birley (Vindolanda CEO) describing excavating the anaerobic layers in 2017.


3D-scanning

Imagine how it would feel to hold an object from the museum!  They are far too delicate to be handled, but with the use of 3D scanning and printing, it is possible to replicate some of these objects.  Dr Rhys Williams (Lecturer at Teesside University and 3D specialist) elaborates on how this works.
