The Seoullo 7017 Skygarden in Seoul, South Korea

Seoullo 7017 Skygarden

Seoul, South Korea

Snaking above Seoul’s thoroughfares is Seoullo 7017 Skygarden, a new pedestrian walkway reborn from a former highway overpass, much in the vein of New York City’s High Line. Its 17 sections feature family-friendly cafés, gardens and even stations for relaxing foot baths. But the structure, designed by Dutch firm MVRDV, is arguably more stunning at night, when illuminated pillars transform it into a glowing ribbon of purple. —Suyin Haynes
