A stroll down (or up) Fifth Avenue still conjures a certain old New York, depicted in classic films and immortalized in vintage postcards. It’s a quintessential Manhattan experience, one that—through May 31—is getting the unapologetically joyful Van Cleef & Arpels treatment, with help from French artist Alexandre Benjamin Navet.

The blocks between 47th Street and 59th Street, while majestic in their own right (St. Patrick’s Cathedral, the Plaza, Rockefeller Center, flagship stores galore…), have been outfitted with 14 three-dimensional floral-themed reimaginings of Navet’s color-happy sketches, each one unique to its particular location. “I like to do something different for every location because the city is different and the energy is unique, and I’m in awe to have the opportunity to express myself on such a beautiful avenue,” says Navet.

Thanks to their size and razzle-dazzle factor, these installations are impossible to miss, but to help you make the most of Van Cleef & Arpels’ vision and this beloved slice of the city, we put together a little walking tour of the Upper East Side.
