Ambitious, historic, spectacular – these are some of the words used to describe the Paris 2024 Opening Ceremony since the first plans were unveiled three years ago.

Set to be the first Olympic Games Opening Ceremony held outside a stadium, the 26 July celebration will transform the French capital into a stadium and theatre as the traditional parade of athletes takes place in boats along the Seine, passing the most iconic Parisian landmarks.

Here is all you need to know about the Opening Ceremony.

When will the opening ceremony be held?
The Opening Ceremony of the Paris 2024 Olympic Games will take place on Friday, 26 July.

The event will start at 19:30 CEST and is expected to last more than three hours.

Why is this ceremony historic?
Paris 2024 will mark the first time in history of the Olympic Summer Games that the Opening Ceremony is held outside a stadium.

Instead of familiar images of athletes marching out along an athletics track, guests and viewers will be treated to a colourful river parade through the heart of the French capital.

The Seine, the city’s main water artery, will substitute for the traditional track, the quays will become spectator stands, while the setting sun reflecting off famous Parisian landmarks will provide the backdrop for the event.

This outdoor concept also makes Paris 2024 the largest Opening Ceremony in terms of audience and geographical coverage.

What is the route of the parade?
The parade route along the Seine is a visual journey through Parisian history and architecture.

The Austerlitz Bridge next to the Jardin des Plantes is the starting point for the flotilla, which will then continue west for 6 kilometres along the Seine, passing under historic bridges and by iconic landmarks, such as the Notre-Dame and the Louvre, as well as some Games venues, including the Esplanade des Invalides and the Grand Palais.

Grouped on the boats with their national teams, the athletes will ultimately arrive opposite the Trocadero – the esplanade across from the Eiffel Tower – where the official protocols will be carried out, the Olympic cauldron lit, and the Paris 2024 Games officially declared open.

How many athletes will take part?
Almost 100 boats carrying an estimated 10,500 athletes will float along the Seine during the parade. The larger of the 206 National Olympic Committees (NOCs) represented in the parade will have boats to themselves, while the smaller ones will share boats.

Camera equipment set up on the decks will allow spectators to see the athletes up close and witness their emotions.

What entertainment performances can we expect?
Thomas Jolly, a French theatre director and actor, is overseeing the Paris 2024 Olympic and Paralympic ceremonies as artistic director.

While most of the entertainment acts remain under wraps, based on the hints so far, we can expect a show on a grand scale with an eclectic mash up of the old and the new. Speaking to the media in January, Jolly said that he wants to showcase the contrasting cultures of France, be that opera or rap, thus bringing together all the pieces that form the nation's diverse cultural identity.

For his part, ceremonies choreographer Maud Le Pladec promised that every bridge along the parade route will have dancers on it. Le Pladec will lead 400 dancers out of the total 3,000 artists who are set to take part in the Paris 2024 Opening and Closing Ceremonies, all decked out in one-of-a-kind costumes by Daphne Burki.

The French television presenter serves as the costume director for the show, leading a team of hundreds of dressmakers, hair stylists and makeup artists. Burki’s focus on sustainability also means there will be many vintage and upcycled pieces used in the ceremonies, mixed in with newer creations.

What will the athletes be wearing?
Artists will not be the only ones showing their style at the Opening Ceremony. With a line-up of luxury brands designing athlete uniforms, expect the Olympians to shine as well.

Team USA mix preppy jackets with jeans for a cool, all-American look, while Italian athletes will show up in casual, dark blue sets. Hosts France worked with a luxury brand to come up with vests and jackets that tie in with the general Paris 2024 look.

Other teams, such as Canada, Great Britain and Sweden, opted for a more athleisure look, all evoking the colour palettes of their national flags.

Some nations went even further with the patriotic details. Mongolian outfits have already created a buzz on social networks for their intricate embroidery and traditional silhouettes.

Brazil and Guatemala’s looks are also sure to turn heads. Brazil’s denim jackets feature animals that are native to the country, while the Guatemalan athletes are dressed up in folkloric hats and bags to make a colourful statement on the Seine.

WHAT ARE THE DIFFERENT WAYS TO WATCH THE OPENING CEREMONY?
Almost 600,000 people will be able to enjoy the Opening Ceremony in person. True to its slogan, “Games Wide Open”, Paris 2024 tried to make the event accessible to as many people as possible by taking it outside of the traditional stadium setting.

There were 222,000 free tickets available to watch the parade from the upper banks of the Seine, in addition to 104,000 paid tickets on the lower quays. This marks the first Opening Ceremony where most spectators will not pay an admission fee – another historic milestone for Paris 2024.

Those in Paris who could not get tickets will be able to watch the Opening Ceremony on 80 giant screens set up throughout the city.

An additional 1.5 billion people from around the world are expected to tune into the television broadcasts of the ceremony.
