The Mayor, Alderman Noel Williams, said: “I am so looking forward to Armed Forces Day 2023 in Larne and particularly the 21-gun salute to mark the reigning monarch’s birthday. It will be a very special occasion this year as it is the first time guns will be fired for His Majesty King Charles III.
“This is an exciting opportunity for residents and visitors to play a part in the birthday celebrations, plus there will be so much more entertainment throughout the day for all ages. Come along, join in the fun and help us recognise the honourable service of the Armed Forces, both past and present.”
The Larne event will begin with a parade to Sandy Bay Playing Fields and a Drumhead Service, concluding that evening with Beating the Retreat Finale.
