The programme for this year's St Patrick's Festival has been revealed with half-a-million spectators expected to line the route of the parade.

Organisers say the 3-day festival will be the most ambitious ever.

St Patrick's Festival quarter will return to Collins Barracks for a second year with an outdoor stage, performance spaces, a mini funfair and food and craft village.

A new opening pageant has been commissioned featuring a collaboration with St Patrick's Festival Community Arts pageant with Macnas, Junk Kouture, Discovery Gospel Choir and many other community groups.

A new strand of the festival this year is Suntas, which means "take notice".

It will feature giant creative interventions on iconic buildings around Dublin as the city turns green.

The giant monsters will be visible by day and illuminated by night.

More than 4,000 participants are expected to take part in the parade on 17 March.

The parade will feature 7 creative pageants, 10 transitional showpiece performances and 15 marching bands from across Ireland, North America and Canada.

There will also be the aerial artists, Fidget Feet in what promised to be a "spectacular high-flying display".

Richard Tierney, CEO, of the St Patrick's Festival said this year's festival is going to be "bigger and better".

"Obviously the parade on the 17th, swiftly followed in the National Musuem in Cathal Barracks for a Ceili Mor," he said.

Ciara Sugrue, Head of Festivals at Fáilte Ireland said: "St Patrick's Festival has an economic impact for Dublin of about €50 million over the course of the festival."

The Festival After Dark is new to the 2023 programme offering with a series of events in Nightclubs post 11pm.

Amongst the artists due to perform over the festival are Mother DJ's, Pillow Queens, Kila and Brass Band, Melts, Katie Kim, Pixie Woo and many more.

This year, Bui Bolg and Kia are collaborating on an exciting new pageant entitled ‘The Future That Moves Us’ featuring an interactive AR element in the parade for the very first time.
