Central Paris goes car-free on Sunday as part of its fight against air pollution.
The French capital's central arrondissements and areas around landmarks such as the Eiffel Tower and Champs Elysees will be free from car noise and exhaust fumes, allowing people to stroll, cycle or skate between 0900 GMT and 1600 GMT.
Exceptions are allowed for taxis, buses and emergency vehicles. Paris has occasionally closed selected roads to traffic in the past, but not as large an area as will be covered on Sunday.
Socialist mayor Anne Hidalgo told the daily Le Parisien that the goal was to show that "Paris can operate without cars".
