The Diana Memorial Fountain was opened by HM The Queen in 2004 in memory of Diana, Princes of Wales who died in 1997. The fountain was designed by Kathryn Gustafson and Neil Porter to reflect Diana's life and is said to symbolize Diana's quality of openness.
The fountain is built from Cornish granite and is a long loop with water flowing from the highest point in two directions before meeting again at the bottom. It's not a gushing torrent of water but more a steady trickle which makes it popular with paddling toddlers, although you are not supposed to climb in. There are three bridges where you can cross the water and children enjoy doing this.
It's a popular spot in Hyde Park but it is not to everyone's taste. I've heard many disappointed cries when visitors first see the memorial as I think we all expect a more traditional fountain. Some have even commented that it looks like a drainage channel but it remains a popular place to visit to remember a popular princess.
