The festival on the frozen river
Two hundred years ago the last "frost fair" took place on the River Thames.
The impromptu festival was organised after the river became frozen and was covered in thick ice between London Bridge and Blackfriars.
Some of the souvenirs from the 1814 event have survived and are now going on display.
BBC London's Sonja Jessup spoke to Georgina Young, a curator from the Museum of London Docklands.
