A Death Gun Salute has been fired to mark the death of His Royal Highness, Prince Philip.
The Duke of Edinburgh passed away on Friday morning at Windsor Castle.
Gun salutes took place across the United Kingdom, in Gibraltar, and on Royal Navy ships at sea on Saturday.
Forty-one rounds were fired – starting at midday and one every minute for 40 minutes.
Amid the coronavirus pandemic, members of the public were encouraged to stay at home for the salutes, which were behind closed doors but broadcast on television and online.
The King's Troop Royal Horse Artillery performed the salute in London, having ridden out from their Woolwich Barracks base onto the Parade Ground.
Thirty-six of the 71 horses pulled a total of six 13-pounder field guns which date back to the First World War.
The same guns were fired for the Duke's wedding to Her Majesty Queen Elizabeth II in 1947 and at Her Majesty's coronation in 1953.

The Honourable Artillery Company's Light Guns at the Tower of London fired at the same time, along with units from Belfast, Cardiff, Edinburgh and British Overseas Territory Gibraltar.
Simultaneously, Royal Navy saluting warships, including HMS Diamond and HMS Montrose, fired their guns at sea to add to salutes from HMNB Devonport and HMNB Portsmouth.
Defence Secretary Ben Wallace said: "His Royal Highness Prince Philip, The Duke of Edinburgh, was a constant supporter and ambassador of the Armed Forces. We celebrate his life of service and offer our condolences to Her Majesty the Queen and the Royal Family."
Chief of the Defence Staff, General Sir Nick Carter, said: "His Royal Highness has been a great friend, inspiration and role model for the Armed Forces and he will be sorely missed.
"The Duke of Edinburgh served among us during the Second World War, and he remained devoted to the Royal Navy and the Armed Forces as a whole.
"A life well lived, His Royal Highness leaves us with a legacy of indomitable spirit, steadfastness and an unshakeable sense of duty. From all of us who serve today and who have served, thank you."
