Supplementary lectures

There is a series of interesting lectures on related subjects being given at Gresham College. This was founded 1597 and hosts free lectures for the general public at the Museum of London, which is on a bus route from Waterloo Station [no cost if you have a bus pass]) that you may find of interest. Each lecture lasts about an hour, with questions. They are all on Wednesdays at 1.00 pm.

Each lecture is self-contained, so there is no need to commit to the whole series. If anyone is interested in joining Celia Gregory to attend a lecture, please contact her on cag.treetops@talktalk.net or phone 644 350 to arrange to travel up together and hopefully buy a reduced train fare. The Museum has a good cafe or one can take sandwiches.

Tickets for the lecture are generally unreserved, and there is free parking in the main University car park.
