Two centenarians will lead the celebrations as a city marks Sir David Attenborough's 100th birthday with a new immersive show on Friday.

Ivor Foster and Nicky Nicholson, both born in 1926, will be among the first people to experience a new 210-degree version of Our Story with David Attenborough inside the Market Hall Immersive Dome in Plymouth.

Born in Stonehouse, Foster remembers the Market Hall from wartime Plymouth, when he worked as an air raid precautions messenger boy, running messages between Stonehouse and Devonport.

Also 100, Nicholson has lived in Plymouth all her life and raised six children after being widowed at just 41.

The immersive dome projection system covers a 210-degree field of view alongside a large sound system.
