Forty-seven local schools constructed a range of different-sized angels to flood the building. They are placed all over the Cathedral, from the gallery to the font.
The pupils made them collectively, with some schools giving a model which has a piece of fabric from every student on it.
Others are papier mache, and some children have written prayers on their angels.
Jane Whittington, a school officer with the Diocese of Guildford education team, told Premier they were made by reception age group students through to age 16-year-olds.
"The smallest ones are about 30 cm high and they're perched on windowsill and little ledges the largest one are just under six foot with quite a lot of them at about real-size child height.
"All the way around the Cathedral we've dotted angels around; some are hiding, peering down from the gallery, some are in the treasury, peering down from ledges and shelves in there, round behind the font and so on.
"So, when people some to visit they will have to hunt for them," she said.
She added that she hopes the angels will attract non-Christian families to the Cathedral to see their children's work.
She told Premier: "We've always had a school art exhibition at the Cathedral over Christmas and we know that lots of children to bring their families to see their art over Christmas."
To launch the display, families have been invited to takepart in a free, family afternoon of child-friendly, angel-themed crafts on Sunday 3rd December, from 1.30-3.30pm.
The organisers encouraged everyone to come dressed as an angel and join in grand finale of singing Hark! The Herald Angels Sing with the Cathedral choir.
The angel display will be up until 8th January.
