The country's earliest St Patrick's Day parade was kicking off while most still slumbered.
The sun had not yet risen on the national holiday when the dawn parade in Dingle, Co Kerry was already under way.
It's a tradition that dates back to the Land War of the 1870s, when there was a curfew on any public gatherings between dusk and dawn. So to get around this, the parade started at one minute to six in the morning and was already over before the sun had risen.
Revellers have maintained the tradition ever since and about 150 diehard supporters lined the streets as the Dingle Fife and Drum band made its way around the town at 5.59am.
"It always has to be before six, that's the tradition," said local publican and member of the band, Fergus O'Flaherty.
"It's a great local tradition that goes back to the time of Cogadh na Talun (the Land War) and is still going."
The traditional starting point is outside St Elizabeth's Hospital, formerly the workhouse. From there it winds its way around the town before heading to St Mary's Church on Green Street for the traditional dawn Mass.
Colm Kennedy from Ashmount has been playing music with the fife and drum band for the past 50 years and has been attending the dawn parade for as long as he can remember.

"Much to my confusion I thought this was a strange time for a rehearsal," Mr Sheridan said on his rude awakening at 6am.
This was the earliest of a total of 17 parades in Co Kerry alone yesterday.
