Lynn’s light shows have been praised for highlighting the town as a tourism destination.
Last week, West Norfolk Council officials announced that the Lumiere series of projected displays would be extended until late November.
And the project’s impact on the town was praised by Vivienne Spikings during Thursday’s full council meeting.
She pointed to national media coverage of the displays as proof of the positive effect on the town.
She said: “How different and how exciting it is now. All the hard work that’s going into these events is really paying off.”
Elizabeth Nockolds, the authority’s cabinet member for culture, heritage and health, said the borough had been promoted on national radio and websites, as well as on trains heading to and from London Kings Cross, the station where trains from Lynn travel to.
She said: “We’ve done a lot of advertising of our borough and it has paid off.”
