Paris boasts an unusual elevated park, La Promenade Plantée, built atop an abandoned elevated railway viaduct in the 12th arrondissement. It starts a block east of the Place de la Bastille and stretches for 2.9 elevated miles. Landscape architect Jacques Vergely and architect Philippe Mathieux designed the Promenade, which opened in 1993 and was the only elevated park in the world until New York's High Line opened in 2009.
It features flowers, trellises, shrubs and trees and has ample benches for relaxing along the way. You can also admire the surrounding architecture—and even peek into a window or two—as you take in the beautiful natural surroundings.
On a warm day, people from the neighborhood sit and chat, a jogger trots by, and office workers enjoy their lunches in the sunshine. At the Bastille end, arts and crafts shops are nestled in the viaduct arches under the parkway, called the Viaduc des Arts.
