Chanel commissioned the structure to house works by about 15 contemporary artists. Each asked to create a work that was at least in part inspired by Chanel’s classic quilted-style handbag. Artists recruited for the project include Sophie Calle of France, Sylvie Fleury of Switzerland, Subodh Gupta of India and the Russian collective Blue Noses.

The challenge, Ms. Hadid said, was to create a pavilion that was visually compelling and could be easily transported. The result is a 7,500-square-foot doughnut-shape structure with a central courtyard. Its lightweight panels can be packed in 51 shippable containers. Skylights admit natural light, and computer-generated lighting casts a rainbow of colors around the base of the exterior that glows day and night.

Many of the artists explored the notion of the handbag as a cultural symbol, often with a dash of irreverence. Ms. Fleury created a giant Pop Art-style quilted handbag lined with pink fur; inside is a makeup compact in which you can view a video of women shooting handbags with guns.

City officials, who are hoping that the art pavilion will be a draw for tourists, described the money that Chanel is donating as a windfall for the park. Asked whether he anticipated criticism for allowing Chanel to advertise one of its products in the park, Adrian Benepe, the city’s parks commissioner countered, “Everything has a sponsor.”

Ms. Hadid, who won the Pritzker Prize — architecture’s highest honor — in 2004, said that she liked the idea that a pavilion “lands, creates a buzz and disappears.”
