The photographer Chloe Dewe Mathews has spent years chronicling that attraction. In her images you will find druids, Anglican priests, Morris dancers mudlarkers, commuters, Hindus, families scattering the ashes of loved ones, fishermen and swimmers all drawn to the Thames as it travels from its source in Gloucestershire to the North Sea.

Here, a group of white-robed Pentecostalists from London in 2013 have travelled to Southend-on-Sea for a full-immersion. When the River Jordan isn’t close by, you find what works.

Thames Log by Chloe Dewe Mathews, £40, is co-published by Loose Joints and Martin Parr Foundation, who will exhibit the work in summer 2021.
