Ryan Tubridy said he was 'emotional' watching a Dublin Castle ceremony over the weekend.
The special ceremony took place on Sunday to mark the centenary of the British handover of Dublin Castle to the Irish.
The event, which was held at the same time as the events of 100 years ago, was attended by President Michael D Higgins, Taoiseach Micheal Martin and Tanaiste Leo Varadkar.
Speaking on Monday morning, Tubridy admitted he was “still struck" by the "emotional" coverage .
“It was so beautiful and so dignified and so elegant,” he told his RTE Radio 1 listeners.
“Hats off to whoever put it all together it was beautifully treated. There was solemnity. I felt very proud, I have to say, watching it.
“Particularly when the Irish flag was flown at full mast and Amhran na Bhfiann was sung. And the president and the Taoiseach and all the various cabinet members were there and guests. ”
UK Ambassador in Ireland Paul Johnston was also a guest, as well as former Irish taoisigh Bertie Ahern and Enda Kenny, and former presidents Mary McAleese and Mary Robinson.
Sinn Fein leader Mary Lou McDonald, Labour leader Alan Kelly and Social Democrats co-leader Catherine Murphy also attended the ceremonial event.
President Higgins unveiled a plaque in Dublin Castle to mark the occasion on the day.
Meanwhile, the handover of power 100 years ago was recalled in a reconstruction of the events of that day by actor Phelim Drew.
Crediting his involvement in the ceremony, the Late Late Show presenter said: “It was exceptional.”
“It really was quite something.”
“It is one of those ‘If I was a history teacher, I'd show that today and then try to organise a tour of Dublin Castle.
“Phelim Drew comes along and beautifully done, he stands in the yard and talks about what happens and his delivery was perfect.
"It didn’t feel like he was acting, it felt sincere. He looked great.
“He looked like he could've been a member of Charles Stewart Parnell's crew with the beard and with his hair slicked back, very classy looking and a really well delivered take on the anniversary.”
He went on to encourage those who missed it to watch it back, adding: “It was just a beautiful, very emotional piece of history and television so I would urge you to watch it back.”
