Two hundred years ago this weekend, work started on cutting the Regent's Canal in north London.
It took eight years to build, and was vital in moving goods across the capital.
Toby Sadler took to the water to find out more:
A human head found in the Regent's Canal in north London has been identified as that of former EastEnders actress Gemma McCluskie.
Investigators used dental records to confirm that it was the head of the 29-year-old who went missing from Bethnal Green earlier this year.
The head had been found by members of the public cleaning the canal at Kingsland Basin on Sunday.
Police have confirmed that all of Gemma's body has now been recovered. Her torso, arms and legs were found in the canal in March.
Her 35-year-old brother, Tony McCluskie, has been charged with her murder.
Candles and flowers have been left close to Regent's Canal where the body of Gemma McCluskie was found.
