The Brighton firm behind the Royal Pavilion ice rink is to instal a 72ft x 72ft maze for the summer.
The maze is due to open on Thursday 4 July and is based on The Selfish Giant, a story by Oscar Wilde.
Shella Parkin, managing director of Laine Ltd, said: “We wanted to create something amazing for the school summer holidays on the eastern lawns in addition to our popular winter attraction.
“Our aim is to create a maze that looks as though it has always been there but somehow ‘out of view’.
“Our design is inspired by a story I’ve loved since I was a little girl and have read aloud to my own children.”
The story is a fairy tale about a giant who doesn’t want to share the garden that he loves with children but learns the error of his ways.
The maze is based on a Roman design and contains almost 400 yards of corridors. It includes giant gardening tools, riddles and sound effects.
It also includes traditional games such as Nine Men’s Morris and Fox and Geese.
The organisers said that it would startle and delight adults and children alike as they try to find their way to the centre of the maze.
The attraction will cost £4 a person. The opening hours will be 11am to 7pm until Tuesday 3 September.
