Cork City Fire Service have a dedicated bonfire crew on duty tonight for the traditional St John's Eve events in the city.
The lighting of fires on St John's Eve has died out in most places, but remains popular in Cork city.
Initiatives introduced by the city council over the past eight years have seen a fall-off in the number of incidents of anti-social behaviour and out-of-control fires.
The city council is hosting free events in five of its parks.
Similar events last year attracted over 10,000 people.
They have also provided skips in many city areas to avoid the annual burning of furniture and tyres on local pyres.
The fire service dealt with 91 fires on St John's Eve last year.
In previous years, it dealt with between 200 and 300 fires on the night.
Gardaí also reported a significant fall-off in the number of incidents of drunkenness and assaults.
