The city's cobbles were brought to life with dance.
A zumba flash mob popped up in Gentleman's Walk on Sunday, surprising shoppers and passerby.
The dancers wearing white t-shirts decorated with pink handprints were raising awareness of breast cancer and raising money for Big C.
Lead by Rachel Evans, a Zumba dance teacher that holds classes across the region.
She was also given the South Norfolk Charity Fundraiser of the Year award.
'I felt this would be a great way to celebrate my award with my students and I also invited other Zumba Instructors to take part,' she said. 'Ömür Abay, an international Zumba presenter flew over from Turkey to take part too.'
People of all ages sprang to life, outside Cafe Nero, and crowds cheered on the enthusiastic dancers.
For Ms Evans, raising awareness of breast cancer has long been an ambition after hearing stories from her many students.
She said: 'In the past 6 months there have been a handful of students who have followed our message of monthly checking and found lumps, all of which I'm happy to report have not been cancerous.
'It seems obvious to me we are making some impact and the people that hear the message are getting into a routine of checking themselves every month. We know that early detection saves lives of course.'
The benefitting charity, Big C, was chosen after Rachel Evans heard some of her students' stories of 'dark days' when battling cancer.
She said: ' It's a mark of respect to support this amazing local charity - last May we raised £4000 - for them in a Zumbathon.'
