Approximately fifteen minutes from Amsterdam Central Station is a huge green copper building. The fascinating construction - often compared to a ship - is superimposed on the IJ-tunnel. It is the largest science center in the Netherlands and bears the name NEMO, wich means nobody. The building is designed by the Italian architect Renzo Piano in 1997. On top you can sit on a "Piazza" and have a look over the harbour and the city. Inside visitors of all ages can playful learn all about science and technology.
