Young people from the area joined representatives from The Royal Parks to celebrate the opening of the new £350,000 playground, which was designed by Farrer Huxley and partly funded by the London Marathon Charitable Trust.
The new playground at Regent's Park is divided into three zones with a combination of natural materials, additional equipment, bespoke play features and additional planting have been used to transform the playground and ensure children explore more creatively.
One of the most exclusive addresses in London, One Cornwall Terrace is a Grade 1 listed mansion overlooking Regent's Park. It has been put on the market for £100m.
A property in Regent's Park has gone on sale for £100 million, and is thought to be the world’s most expensive terraced house.
It boasts seven bedrooms, 11 reception rooms, nine bathrooms, a private gym and a garage with number-plate recognition that can accommodate two cars.
The Grade I listed building, whose lights are controlled by an iPad, also has a heated indoor swimming pool complete with spa, sauna and his-and-hers changing rooms.
The mansion is most famous for serving as the official London residence of the New Zealand High Commissioner from 1955 until the Seventies.
The aim of the 10K run in Regent's Park today is to enable families and friends to remember their missing loved ones and to raise funds for the charity's 24 hour phone line.
Among those taking part will be Missing family representatives Peter Lawrence, father of missing Claudia Lawrence, and Rachel Elias, sister of missing Manic Street Preacher Richey Edwards.
An estimated 250,000 people go missing in the UK every year.
The run begins at 9am on The Broadwalk, Chester Road, Regents Park.
