The Duke of Edinburgh’s 97th birthday celebrations was marked with a thundering gun salute in Carrickfergus.
The Duke enjoyed his birthday in private on Sunday.
And on Monday twenty-one rounds were fired from three guns positioned below Carrickfergus Castle.
The guns, which have been used by the army in battle zones throughout the world, were supplied and operated by 206 (Ulster) Battery Royal Artillery.
Among the special guests was Mrs Joan Christie CVO OBE, Her Majesty’s Lord-Lieutenant for the County of Antrim.
In 1961 the Queen and The Duke of Edinburgh visited Carrickfergus for the start of a two-day visit to Northern Ireland.
