Dublin Fire Brigade firefighters were called out to 230 incidents between 4pm and 6am.
These included fires at (from top) Malahide, Ballymun, Darndale, Kildare (pic 4 and 5) and Fortunestown.
Greg O’Dwyer, assistant chief fire officer at Dublin Fire Brigade, told Morning Ireland earlier today that there were also 298 ambulance call-outs overnight.
He said this was a decrease in incidents compared to previous years and said no firefighter suffered any injury last night.
However, he said, throughout the city, attempts were made to stop the firefighters from entering some estates.
He said at the entrances to some estates, they found that either cars had been driven into fires or set alight or bonfire material was set alight.
