The Diana, Princess of Wales Memorial Fountain, opened by HM The Queen, has been visited by over two million people since 2004, making the memorial one of London’s most popular free tourist attractions.
The design expresses the concept of 'Reaching Out ‒ Letting In'. This is based on the qualities of the Princess of Wales that were most loved: Her inclusiveness and her accessibility. The fountain has been integrated into the natural slope of the land in Hyde Park using as a starting point the existing ground level around the canopies of the mature trees surrounding the site. The memorial stands out as a light-coloured ring in the landscape which contrasts with the surrounding meadow area and planting. Specific features create different water effects like 'Chadar Cascade', 'Swoosh', 'Stepped Cascade', 'Rock and Roll' and a still basin at the bottom to reflect the various qualities of the Princess' life.
In collaboration with hydraulic engineers a water system was designed, which is not only sustainable but also assists the ecology of the adjacent Serpentine lake. Fresh water is pumped out of a 100m deep bore hole and held in a tank below ground. The water circulating in the fountain is not treated and is monitored on a continuous basis to ensure water quality. Ten percent of the water flow is drained into the Serpentine helping to keep a constant flow of water within the lake and eliminating the build up of algal bloom near the bathing area. The tank is topped up with ground water on a regular basis.
