We are grateful to welcome John Deverell who has kindly stepped in to replace the scheduled lecture by Shaun Richardson who can no longer present his work on his research into the landscape at Burton Constable before Constable. John is a long standing and active member of ERAS. On this occasion he will be presenting details on his research into the prehistoric entrenchments of East Yorkshire. Due to Covid 19 restrictions this lecture will take place online and will be open to ERAS members only. If you are a member and wish to view the presentation you should ensure your email address is registered with the Membership Secretary by emailing [email protected].
