Paris Rehearses Seine River Opening Ceremony for 2024 Olympics

Officials test logistics and security with a parade of 55 boats, preparing for a unique open-air event.

The rehearsal involved 55 boats traveling from Pont d'Austerlitz to Pont d'Iéna, near the Eiffel Tower.
Around 200 Olympic delegations will participate in the actual ceremony, with over 80 boats on a 6-kilometer route.
Security remains a top concern, with plans for 45,000 police officers and 18,000 soldiers on the day of the event.
French officials have invested $1.5 billion to improve the Seine's water quality for Olympic events like swimming and triathlon.
The ceremony's final rehearsal will involve the full armada of boats and is expected to draw 100 world leaders and 300,000 spectators.
