Today in Cardiff Castle at 13:00 BST, a gun salute of 96 rounds will be carried out by 104 Royal Artillery Regiment to mark each year of Her Majesty Queen Elizabeth II’s life.
Across Wales between 12:00 and 13:00 churches are being encouraged to ring muffled bells.
Cardiff City Hall will have a book of condolence opened to the public from 14:00 and floral tributes to Her Majesty can also be left.
The Senedd is set to be recalled.
Presiding Officer Elin Jones said: “That will be my first duty as Llywydd and we’ll be looking at recalling the Senedd over the weekend, and throughout the morning [Friday] I will confirm the exact time of that.”
Ms Jones told BBC Radio Cymru: “The Queen has opened every Senedd since devolution in 1999. She made certain that the Senedd’s constitutional importance got recognised… so it’s important that we recognise her contribution too.”
