Monthly Talks at London Canal Museum
Our monthly talks start at 19:30 on the first Thursday of each month except August. Admission is at normal charges and you don't need to book. They end around 21:00.
November 7th
The Canal Pioneers, by Chris Lewis. James Brindley is recognized as one of the leading early canal engineers. He was also a major player in training others in the art of canal planning and building. Chris Lewis will explain how Brindley made such a positive contribution to the education of that group of early "civil engineers".
December 5th
Ice for the Metropolis, by Malcolm Tucker. Well before the arrival of freezers, there was a demand for ice for food preservation and catering, Malcolm will explain the history of importing natural ice and the technology of building ice wells, and how London's ice trade grew.
February 6th
An Update on the Cotsword Canals, by Liz Payne. The Stroudwater Canal is moving towards reopening. The Thames and Severn Canal will take a little longer. We will have a report on the present state of play.
March 6th
Eyots and Aits-Thames Islands, by Miranda Vickers. The Thames had many islands. Miranda has undertaken a review of all of them. She will tell us about those of greatest interest.
