World Expo: Connected Roof Rings Make World's Largest Wooden Building

OSAKA, Aug 22 (Kyodo) - As preparations ramp up for the 2025 World Exposition in Osaka, the symbolic giant wooden roof, known as the "Grand Ring," was visible in its full circular form at the venue on Wednesday.

The ring is set to become one of the world's largest wooden structures, with a circumference of approximately 2 kilometers and a maximum height of around 20 meters, according to the expo organizers. Construction is expected to continue through February next year.

The area beneath the roof will serve as a main promenade for the expo site, providing shelter from rain and sunlight during the event, which runs from April 13 to Oct. 13 next year. The rooftop of the ring will offer views of the surrounding pavilions of international participants.
