RTE's 'Reflecting the Rising' staged over 300 free events on Monday to mark the centenary of the Easter Rising.
Billed as the biggest public history event ever staged in the state RTÉ Reflecting the Rising did not disappoint.
In terms of numbers it is topped only by the visit of Pope John Paul II in 1979 which attracted one million people to the Phoenix Park.
The national broadcaster has revealed that a further 500,000 were in the city on Sunday for a huge military parade through the streets.
The national broadcaster offered hundreds of talks as well as debates, music, theatre, films, walking tours and multi-media displays that explored the events of Easter Week and its aftermath as well as life at the time and the ensuing 100 years.
The day culminated with the spectacular stage show Centenary at the Bord Gais Energy theatre.
Some of Ireland’s best known singers, musicians and performers including Imelda May, Jack Lukeman, Gavin James and Colm Wilkinson came together for the special one-off cultural celebration to mark the 100th anniversary of the 1916 Rising.
Centenary had a cast of over 600 performers including 21 choirs, 18 dancers, 6 aerial dancers and the RTÉ Concert Orchestra featuring original music composed by Joe Csibi.
The programme attracted an audience of 491,000 viewers on RTÉ One representing 35% of the available audience.
To date, there have been 29,700 streams (live and on demand) of Centenary on RTÉ Player- 61% of streams from domestic audiences and 39% from international audiences.
Glen Killane, Project Lead, RTÉ 1916 and Managing Director of RTÉ Television said: "The weekend's output was produced by staff across RTÉ in collaboration with the independent production sector, Ireland 2016 and arts and cultural organisations throughout the country."
He continued: "RTÉ is also proud that our coverage of the official state ceremonies was carried by broadcasters at home and abroad, ensuring that they could be enjoyed by the widest possible audience and showcasing our country from the US to China."
In total over three million tuned into RTE television over the Bank Holiday weekend.
A garda spokesman said: "A large policing plan was put in operation for the 1916 Easter Rising Commemorations. As you can appreciate we won’t be going into detail for security and operational reasons.
"However the Garda operation was supported by the Air Support Unit, the dog unit and other National Support units and Gardaí at District level.
"This weekend’s event was attended by a large number of people and from a policing perspective was very successful without any incident of note."
A spokesperson for RTE said: "RTÉ Reflecting the Rising in partnership with Ireland 2016 created an event which was ambitious in both scale and vision, delivering a diverse programme of activities and cultural experiences across the city, and we are delighted that so many people shared the day with us."
"All ages and generations came out to celebrate and remember together, and thousands more joined us both at home and abroad on our broadcast services throughout the day."
