Lynn’s light shows will be switched off tomorrow night to mark the annual Earth Hour.
The projections will be turned off at 8.30pm on Saturday, which coincides with two candlelit vigils organised by members of Lynn’s Klimate Concern campaign group.
The vigils will take place outdoors in the Saturday Market Place and indoors at the Friends Meeting House in Bridge Street.
They will be followed by a social event at the meeting house from 9,30pm.
Daphne Sampson, of Kilmate Concern, said: “We are proud to take part in Earth Hour and are excited to be involved with such a great and inspiring event.
“Everyone can make a difference to help protect our planet and we all have a key role to play.
“We are delighted that the borough council have been so positive about playing an active role in this too.”
Brian Long, West Norfolk Council cabinet member for environment, said: “We hope that lots of people will notice our light shows are turned off, and be inspired by it.
“Earth Hour isn’t designed to have impact through an hour of energy saving.
“It’s to make us think about the issues facing the planet, and remind us that together we have the power to make change happen.”
