Large crowds packed into the heart of Lynn on Friday night for the annual Fawkes in the Walks festivities.
Organisers estimate that around 10,000 people flocked to the park for the seventh annual show.
And they have thanked revellers for their patience as the firework display was delayed to allow latecomers to enter the park safely.
Borough mayor Colin Manning lit the bonfire before a spectacular firework display by the Wisbech-based firm White Lightning Pyro lit up the night sky.
David Pope, the borough council’s cabinet member for leisure and public space, said: “It was a fantastic evening, and I’m delighted so many people came along. The hard work of everyone involved helps to make it such a great event.
“I’d especially like to thank all the volunteers, without whom the event couldn’t be such a success.”
The authority also thanked organisers of the town’s regular Park Run events in the Walks, after some of their participants helped with a litter pick on Saturday morning.
Persistent rain in the hours ahead of the show meant underfoot conditions were perhaps a little softer than ideal during the evening.
But, although one area has been churned up by a ride, officials say the park is in very good condition following the event and little remedial work will be needed.
The council has also announced Friday, November 4, as the date for the 2016 spectacle.
