But the town's illuminations have now taken on a very different light, having been transformed into Christmas decorations for the festive period.
The new light shows will be shown every evening from 5pm until 10pm at five of the six Lynn Lumière sites, and will run into the New Year.
As part of the project, a clip with sound featuring Donald Duck from the Disney film 'Mickey's Twice Upon a Christmas' will be projected onto 1-3 Tuesday Market Place, and 18 New Conduit Street will show a clip from the Disney film 'Frozen', also with sound.
St Nicholas' Chapel, Greyfriars Tower and the Minster all get new Christmas-themed projections, while Julia Dantonnet's light show 'Savages', celebrating the life of Frederick Savage, returns to the Custom House.
Elizabeth Nockolds, West Norfolk Council's cabinet member for culture, heritage and health, said: 'The light shows are one of Lynn's most talked-about attractions, and I am delighted we have new shows beginning.'
