Tucked between the busy shopping corridors of Damrak and Nieuwendijk, this eye-popping, 165-foot-long passageway is an Instagrammer’s dream: a wonder of colored mosaic tiles, gilded chandeliers, stained glass, and patterned mirrors. A trio of Dutch artists reimagined the bland 19th-century arcade in 2016, turning the massive, barrel-vaulted ceiling into a underwater world inspired by the city’s canals, complete with fish, anchors, and of course, a bicycle. Other amusing details include clog-shaped wall sconces and a fountain inside in the mouth of a large fish.
