The West Essex Archaeological Group will host a presentation by TV presenter Gustav Milne on 13 May (7.45pm; free), looking at the siting and development of the ancient port of London. The talk will examine a wide range of records, including the geological and physical features of the area together with social, political and trading changes. Gustav – who is a presenter on the Channel 4 series Britain at Low Tide – has been a lecturer at UCL since 1991. The event – known as the Rudge Lecture – will take place at Woodford County High School. “The Rudge Lecture is free to all, and members of the public are warmly invited to come along to enjoy the talk. It is presented annually in honour of our first secretary and generous benefactor Dr Earnest Rudge,” said a group spokesperson. Visit weag.org.uk
