The temporary attraction will appear in the western end of the Nave at Norwich Cathedral between 7th and 18th August 2019 as part of a special exhibition called Seeing It Differently.
Rev Canon Andy Bryant, Canon for Mission and Pastoral Care, said: “A cathedral may not be the natural home of a helter skelter but that is precisely part of the draw.
“We will be doing what cathedrals have always done: helping people see things differently and make connections with the things of God.”
Guests are being promised “unique” views from the slide of the historic cathedral which boasts a medieval roof depicting Biblical scenes.

During the special event, visitors will be able to lie down on yoga mats in the east end of the nave and admire the cathedral’s 69ft-high ceiling.
