Watch: Jubilee celebrations day by day
The network of flaming tributes will stretch across the UK and the Commonwealth, as the monarch celebrates 70 years on the throne.
Here is everything you need to know about the jubilee beacons, including how to see them.
Where are the jubilee beacons being lit?
More than 3,000 beacons will be set ablaze on Thursday, 2 June, to kick off four days of Platinum Jubilee celebrations.
For the first time, beacons will be lit in all 54 Commonwealth capitals, spanning five continents.
The first beacons will be lit in Tonga and Samoa in the South Pacific, and the final one in the central American country of Belize.
In the UK, beacons will be located at landmarks including Buckingham Palace, the Tower of London, Windsor Great Park and Hillsborough Castle.
They will also be illuminated at the Queen's estates of Sandringham and Balmoral, and on top of the UK's four highest peaks.

What is the meaning behind the beacons?
The lighting of beacons is a long-standing tradition at royal events such as jubilees, weddings and coronations.
They were previously lit in 1977, 2002 and 2012 to celebrate the Queen's Silver, Golden and Diamond Jubilees, as well as her 90th birthday in 2016.

The event's official website states that beacon chains have "become a symbol of unity across towns, borders, countries and continents".
When is the Buckingham Palace beacon being lit?
The principal beacon will be outside Buckingham Palace, in the form of a spectacular 21-metre tall Tree of Trees sculpture, on Thursday evening.
It will be illuminated by a senior member of the Royal Family, who is yet to be named, and images will be projected on to the Palace.
The special event will be broadcast on BBC One from 8pm, with coverage hosted by Kirsty Young.
American musician Gregory Porter will lead a performance of a specially composed song, A Life Lived With Grace, alongside the London Community Gospel Choir.
The new song, written by Lucy Kiely from Australia and composed by Vincent Atuyei Chinemelu from Nigeria, won the Commonwealth Resounds Competition.
It will be performed by choirs across all 54 Commonwealth countries.
Grammy-winning singer Porter said: "I am so excited to be part of this important celebration of the lighting of thousands of beacons across the UK and the Commonwealth."
