Archaeology is full of techniques I had never heard of prior to blogging about this dig! Levelling is the latest technique that I have been exposed to.
Levelling involves measuring each part of the dig against sea level. It involves using a Level to check the height each part of the excavation comes to. Recording this against sea level means that two parts of the dig that may not appear to be the same depth below ground can be measured. If they are at the same depth (or height, depending on how you want to describe it) they are most likely from the same era. Using this method means that all the areas excavated can be checked against each other and may reveal that some parts of the church were built after others.
Keep up to date with the progress of the Grey Friars Dig Part II throughout July 2013 via regular updates on this site. The body of King Richard III was discovered here in 2012 – who and what else lies beneath this now-famous car park?
