A new exhibition looking at the capital's hidden waterways is set to open at the Museum of London Docklands.
Secret Rivers looks at lost waterways such as the Effra, Walbrooke and Neckinger which have all played crucial but very different roles in how the city has developed.
The show includes historic artifacts, digital works and drawings to show what different rivers were used for.
For example, visitors can see a Medieval three person toilet seat which was used over the River Fleet when it became an open sewer. The Fleet would later be buried as part of London's Victorian sewer system.
The exhibition also looks at how some of London's lost rivers have been resurfaced and incorporates campaigns where people have called for historic waterways to be returned to the streets, like the Tyburn in Mayfair.
Co-curator Thomas Ardill said it shows just how much of a river city London is and how important those waterways have been.
"You can't know London without understanding its rivers," he said.
Secret Rivers, which is free to view, opens to the public on Friday and will run until 27 October.
