The Joy of Life fountain depicts two bronze figures holding hands while appearing to dance above the water, with four bronze children emerging from the pool.
It is located next to Aldford Street North Gate, alongside Park Lane.
The fountain was designed by T. B. Huxley-Jones and dates from 1963, when Park Lane was widened. It was donated by the Constance Fund to replace the Boy and Dolphin Fountain which previously stood on this spot.
This part of Hyde Park was once a much-admired Victorian sunken garden created in the 1860s. Before that it was a reservoir supplying the royal palaces with drinking water.
In 2008, the charity, Marie Curie Cancer Care, planted 60,000 daffodil bulbs around the fountain to celebrate its 60th anniversary.
