The property’s Grade I-listed South Terrace is being restored in a £3.4 million series of works, which will last for five years.
The National Trust says, ‘What could be a time of disruption is being turned into an advantage, as the slide offers visitors to Cliveden an original and unexpected experience – as well as a totally new way of looking at the house and garden.’
Scaffolding surrounds the staircase, but this is topped by a 6.5m-tall walkway, which encases the staircase on all sides, giving views of the Cliveden estate.
Visitors can then slide from the walkway to parterre garden.
National Trust visitor experience consultant Sam Willis developed the project. She says, ‘By offering visitors the chance to slide down into the historic garden, we know they will go home having had a great time, and also having engaged with the serious side of the work.’
The viewing walkway and slide will be in place until December, before moving to a new home in Cliveden’s woods.
