Prince Philipwas honored on Saturday with a 41-gun salute across the United Kingdom.

To mark the death of the Duke of Edinburgh, starting at noon local time, rounds were fired at one-minute intervals from The Tower of London, Edinburgh Castle, Cardiff Castle, Hillsborough Castle and at sea.

Although the tradition of gun salutes has evolved over the years, the tradition goes back to the 16th century.

“Ships of the Royal Navy used to, on entering a friendly port would fire off all their cannons to show that they had no loaded guns and therefore weren’t a threat,” explained Adjutant Captain Josh Bate in avideoposted on the British Army’s social media account over the weekend. “In response the friendly port would then fire their guns to show that they acknowledged the salute and also weren’t a threat to the ship coming in.”

“That’s evolved over the past 100 years, and now it’s just a more general sign of respect and we fire a different number of guns depending on who we’re paying our respects to,” he added.
