The Crown Jewels will be projected on to the Tower of London before touring UK landmarks under plans to tell the story of coronations to thousands of people.
The jewels will be projected on to the famous London landmark in autumn before touring the length and breadth of the country.
The Crown and Coronation display, produced by Historic Royal Palaces and Luxmuralis, aims to explore the history of coronations in an immersive musical and visual show.
The Government has also announced new screening sites for the King and Queen Consort’s coronation, bringing the total to 57, with more than 100,000 people expected to watch the ceremony live in their home towns.
To mark the coronation weekend, communities are being encouraged to come together for street parties on the Sunday after the service at Westminster Abbey on Saturday May 6.
More than 32,000 coronation big lunch packs have been ordered, with around 50,000 neighborhood events planned, which are set to be attended by millions of people.
There will also be hundreds of thousands of opportunities to take part in The Big Help Out on the Bank Holiday Monday granted to celebrate the coronation.
The project aims to ensure the coronation leaves a lasting legacy in communities by inspiring and recruiting a new generation of volunteers.
Opportunities include the chance to volunteer with the Scouts, Royal Voluntary Service, Guide Dogs and the smallest local volunteering groups.
Culture Secretary Lucy Frazer said: “The coronation marks the beginning of a new chapter in our magnificent national story.
“It promises to be full of memorable experiences for the whole country, with millions of us bearing witness to a moment of history for the United Kingdom and the Commonwealth.
“Every part of the United Kingdom should have a chance to see and feel the joy of the coronation, and this giant light projection will give communities the chance to see precious centuries-old royal treasures up close over the next year.
“With less than a month to go until coronation weekend, there are countless opportunities for people to be part of it – whether it’s watching the service on a big screen in your community, hosting your own Big Lunch for family, friends and neighbors or volunteering in The Big Help Out to give something back.”
Lindsey Brummitt, program director at the Eden Project, home of The Big Lunch, said: “It is a fantastic way to celebrate where you live, be part of history and even fundraise for a charity or cause you care about.
“Bust out the bunting, knock on a neighbor’s door and get to know one another a little better over a tasty snack – it’s such an easy way to be part of everything.”
The Tower of London will also delve deeper than ever before into the history of the Crown Jewels with a new exhibition.
The display in the Jewel House, where the priceless collection is kept under armed guard, will explore the origins of some of the precious objects for the first time, including the controversial Koh-i-noor diamond.
It marks the first major change to the home of the Crown Jewels for more than a decade and will open to the public just weeks after the coronation.
