They are inviting the public to come and see what’s been hiding below the water. A platform will be opened on Saturday and Sunday which hovers less than a metre above the canal bed.
7.5 million gallons of water has been drained from Regent's Canal along a 1km stretch between Johnson Lock and Limehouse Basin in east London. The move was taken to allow repairs to be made to large holes which have developed in the canal wall.
The bottom isn’t all ancient shopping trollies though, a 70-year-old unexploded grenade was also dredged up.
The annual cost to the charity of cleaning up litter on London waterways last year was more than half a million pounds.
Restoration on the canal is scheduled to finish on December 19.
