A West Norfolk firm said it wanted to make its final mystery light-up event a real “showstopper”.

A spokesman for Jak Ropa Professional, the events and entertainment company behind the four-weeks of mystery light tributes, said illuminating the grain silo at King’s Lynn docks was a “great challenge” and its most “exciting light-up” tribute for the NHS and key workers.

“It’s one tallest buildings in and around King’s Lynn and seen for miles all around, so we knew this would be a real showstopper. 

“With this being the final location along with ABP Ports and Javik Laser Creations, it was an opportunity for us all to say thank you to King’s Lynn for everyone doing their part during these difficult times.

“I feel very proud to have delivered what I hope is a memorable vision to some of Lynn’s iconic buildings and brought joy to all that has seen them,” the spokesman said, praising everyone who had helped with the projects. 

One of the thank you messages.

The light-ups, held on Thursdays after Clap For Our Carers, have seen the lighthouse at Old Hunstanton,  church ruins at Bawsey and Palm Paper at Lynn flooded with colourful messages.

But there may be more to come after the organisers said they were working on another big UK project.

The spokesman said it would be something that had not been done before.

Any businesses who like to support the ambitious project have been asked to get in touch.
