French President Emmanuel Macron declared the Olympic Games open on Friday

French President Emmanuel Macron declared the Olympic Games open on Friday after a soaking wet ceremony in which athletes were cheered by the crowd along the Seine, dancers took to the roofs of Paris and Lady Gaga sang a French cabaret song.

France’s three-time Olympic gold medallists Marie-Jose Perec and Teddy Riner then lit the Olympic cauldron, suspended on a hot-air balloon, before Canada’s Celine Dion sang Edith Piaf’s “Hymn to Love”, in her first public performance in years, drawing huge cheers from the crowd.

The 30-metre (98 ft) high balloon carrying a 7-metre diametre ring of fire took to the air and was hovering dozens of metres above the ground.

It will be in the air from sunset until 2 am local time every day, organisers said.

“We are so proud of this show, I’m so proud that sport and culture were celebrated in such a fantastic manner tonight, it was a first and the result was fantastic despite the rain,” Paris 2024 organising president Tony Estanguet told reporters.

A fleet of barges took the competitors on a 6 km-stretch of the river alongside some of the French capital’s most famous landmarks, as performers recreated some of the sports to be showcased in the Games on floating platforms.

It was the first time that an opening ceremony has taken place outside a stadium, adding to the headaches for a vast security operation, just hours after a sabotage attack on the high-speed TGV rail network caused travel chaos across France.

“I invite everybody: dream with us. Like the Olympic athletes, be inspired with the joy that only sport can give us. Let us celebrate this Olympic spirit of living in peace,” International Olympics Committee President Thomas Bach said as the ceremony came to an end at the foot of the Eiffel Tower.

More than 10,500 athletes will compete at the Olympics, 100 years since Paris last staged the Games. Competition started on Wednesday and the first of the 329 gold medals will be awarded on Saturday.
