Birmingham City Council said it was delighted at the success of the city's festival spectaculars, and said the weekends' events were the most popular ever.
On Saturday, the three-day ArtsFest spectacular came to a climax with a spectacular fireworks display over Centenary Square, following a barnstorming performance by the City of Birmingham Symphony Orchestra.
And on Sunday, Millennium point played host to more than a thousand sporty school-children for the SportsFest keep fit event fighting against childhood obesity.
They were the most popular events to be held in Birmingham, with more than 200,000 locals and visitors coming into the city over the three days.
A capacity crowd of 15,000 saw the centrepiece of the weekend, the Classical Fantasia, performed by a collaboration between the CBSO and Birmingham Royal Ballet.
Other very popular events included the Blast performance at the Eastside Curzon Street Station, which blew away more than 3,000 people with a raucous visual and sonic performance.
And 2,000 young people enjoyed the latest up-and-coming indie rock bands through the night on a stage in Victoria Square.
The SportsFest day was established four years ago to help in the fight against childhood obesity.
It saw Millennium Point split into "zones" for sports including football, netball, tennis, hockey, athletics, golf and even boxing - the first time the sport has appeared.
Guest of honour was Olympic heptathlon gold medallist Denise Lewis, who spent most of the day looking round the exhibitions.
As well as giving a quick demonstration of her athletic skills, she also tried her hand at boxing and a few rounds of golf.
"It's been wonderful to be a part of this year's SportsFest, and I've really enjoyed the event," said Lewis. "It's so good to see so many young people enjoying sport, and I hope they go on to join local clubs and make sport a central part of their lives."
Councillor Ray Hassall (Lib Dem Perry Barr), cabinet member for Leisure, Sport and Culture, said he was delighted at the weekend's success stories.
"The UK's largest free arts festival has been a resounding success, with hundreds and thousands of local people and visitors enjoying the best that the country and the Midlands have to offer in arts and culture.
"And SportsFest was very successful because it was all about giving young people an opportunity to try a variety of sport and giving them a chance to find out how they can get fitter and be healthier."
