Cornwall will be home to the longest festive light tunnel in the UK this Christmas, it has been claimed.

Work is under way to illuminate the tunnels below The Shipwreck Treasure Museum at Charlestown.

More than100 metres of passageways beneath the Charlestown attraction will be lit up to celebrate the festive season.

This year’s event will see6.5 kilometers of cabling and 60,000 lights adorning the subterranean walls. The three month build will be finished in time for the launch next Wednesday, December 3.

The attraction said: "This immersive experience will see families walking through the wardrobe into an enchanted Narnia landscape, surrounded by a frozen forest with snow covered branches.

"Then journey through a neon forest with trees that glow in the dark and venture into the spectacular Northern Lights installation."

Lynné Raubenheimer installing the Tunnel of Lights at the Shipwreck Treasure Museum in Charlestown

In parts of the experience visitors can even feel the snow falling as they meander through the Christmas trees.

Behind the creation is Lynné Raubenheimer, who has more than 15 years of experience working in theatre, TV and film productions in the UK, Europe and India.

She said: "This is a chance to escape the reality of the past year and to lose yourself in colour, imagination and fantasy.

“We have also ensured a series of extra precautions and additional safety protocols are in place to ensure the visit fully complies with government guidelines."

Tickets to visit the Tunnel of Lights must be booked in advance via shipwreckcharlestown.co.uk as there is limited availability.

It will be open to the public from December 3 until until January 10 and admission will include access to the museum.

Located in the UNESCO World Heritage Site of Charlestown, the Shipwreck Treasure Museum is home to one of Europe’s largest collections of shipwreck treasures with over 8,000 artefacts in their collection, including the only intact barrel of coins ever recovered from the seabed.
