Soldiers killed in the conflict in Iraq are being remembered alongside the war dead from the 20th century at services across Wales.
Rhodri Morgan and Peter Hain are attending the national service
In Llandudno, the name of Lance Bombardier Llywelyn Evans is being added to the town's seafront cenotaph, the first addition since World War II.
The 24-year-old Royal Artilleryman was one of the first casualties of the war, dying on the first day of the conflict in a helicopter crash which killed 12 servicemen.
First Minister Rhodri Morgan and the Welsh Secretary Peter Hain attended the National Remembrance Day service in Cathay's Park, Cardiff at 1030 GMT.
Inmates at nearby Cardiff prison marked a minute's silence for the fallen during their regular Sunday morning service.
The Bishop of Monmouth, Dominic Walker, led a service following a parade at the cenotaph in Newport starting five minutes before the traditional silence at 1100 GMT.
In Swansea, the Rembrance Day parade took place in the afternoon, moving from Kingsway to St Mary Church for a service.
The service in Llandudno paid special tribute to Llywelyn Evans.
Members of his regiment and friends from Llandudno Rugby Club passed on watching Wales take on England in the rugby world cup to attend the service.
Some 2,000 people gathered at the north Wales town's seafront cenotaph on Sunday morning to dedicate a plaque bearing his name, which has been added to the war memorial
Llywelyn Evans was one of the first casualties of the war
There was applause as his parents and fiancée, and brother Lee who had served in Iraq in the same Royal Artillery commando unit, laid a wreath.
Soldiers from his unit, specially invited to the Remembrance Sunday ceremony, also laid their own wreath to his memory.
Billy Evans, President of the Llandudno branch of the Royal British Legion, had said: "What was so tragic about Llywelyn's death is that it was an accident.
"He must have been a tremendous soldier after hearing the tributes that were paid to him by people at his funeral, which included his commanding officer."
