Above a tunnel overseeing the IJ, NEMO is the largest science museum in the Netherlands. It’s a showcase of how scientific phenomena influence daily life. Different sections of the museum deal with technology and engineering, ICT, and bio- and behavioral sciences. This is a place to take kids and is best for those ages 11 and below—teenagers will probably get bored. During summer it has a panorama roof terrace on its roof with deckchairs with free entry.
