Halloween night was one of the quietest in recent years, according to gardaí. No serious injuries were reported at bonfires around the country, and gardaí and Dublin Fire Brigade said none of their personnel was injured or attended to any "out of the ordinary" incidents.
Dublin Fire Brigade said that while all its units were busy from early evening, with some extinguishing large bonfires, the night passed peacefully compared to those of previous years.
A spokesman for Dublin City Council said the clean-up around the city could take two weeks and cost up to €500,000, broadly in line with last year. Council crews worked from first light yesterday to clear debris from sites with large bonfires.
Some of the larger bonfires were dismantled by council workers early on Monday, and illegal bonfire numbers were expected to reach around 350, in line with last year.
"A lot of our work will depend on the volume of calls we get from people in coming days relating to the condition of public places where bonfires were held," the council spokesman said.
"This year we put a greater emphasis on community festivals with music and fireworks, but we would still estimate that the clean-up could cost as much as last year. It may be lower, but we won't know that until later in the week."
Three divisions of the council were involved in the clean-up, including the parks and landscaping section, housing maintenance and waste management.
The Irish Society for the Prevention of Cruelty to Animals (ISPCA) said is was preparing to reunite hundreds of frightened dogs with their owners.
"When dogs hear bangers or shots, they get afraid and they have a tendency to run and run, and they don't care what gets in their way," said midlands ISPCA officer Paul McCormack.
"Three dogs were killed over the weekend, because they just ran out in front of cars.
"Over the next few days we will get many calls from people saying that dogs have wandered into their homes. We will try to reunite the animals with their owners."
