Every year as spring eases in to summer, urban areas around Amsterdam transform into city “beaches”. BovenNEMO (‘above NEMO’) sits atop NEMO Science Centre on Amsterdam’s largest roof terrace. The huge sea-green ship like structure is nearly impossible to miss just east of Central Station. As entrance to the deck is free, guests can come as they please without having to enter the museum and bask in the sun. There are lounge chairs lining the terrace next to sand pits, giving it the beach feeling.
