A pulsating video tunnel of of LED lights, created to emulate the Aurora Borealis as part of a city's Christmas attractions, is believed to be the largest of its type in Europe, organisers say.

The 45m (148ft) visitor experience features more than 8km (five miles) of cabled LED lighting with 57,400 bulbs.

Project manager Jonathan Bradford said the tunnel was the first of its size in Europe and was "unique" as it contained RGB LEDs "somewhat like a TV screen on a sheer scale".

"It's so bright we can only actually have it running at a maximum of 70% of its potential output."

Costing about 拢60,000, the attraction was funded by local businesses in Norwich to attract visitors from across the UK to the historic city over Christmas, in the hope that they will return for "staycation" breaks in the New Year.

The tunnel went temporarily dark on Wednesday when it was vandalised, but engineers repaired it within 36 hours.

Visitors have described it as "magical" with hundreds posting #tunneloflight selfies on social media.
