Listen again to Dr Liam Herringshaw's lecture at the University of York on Thursday 19th February 2015.
We know plenty about the history of York, but what about its prehistoric origins?
In this talk, geologist Dr Liam Herringshaw will explain how Ice Age glaciers dictated the location of the city, how ancient seas controlled what it is built from, and why it became an international centre of geological research.
