The Olympics begin in Paris with river parade and concerts amid rain

One of the world’s most famous singers, Lady Gaga, performed near Notre-Dame Cathedral, including a French cabaret song in her repertoire.

Dancers performed on rooftops across the city, making the opening ceremony a truly auditory and visual spectacle.

Boats carrying athletes made a long procession along the 6-kilometer riverbank, greeting spectators by some of Paris's most famous landmarks.

For the first time, the Olympic opening ceremony was held outside a stadium, necessitating extensive security measures.
