The NEMO is a technical museum, its name is short for: New Metropolis Science and Technology, located on a small portion of land in the old port of Amsterdam. It is built on top of the IJ-tunnel. Surrounded by water, the building has the shape of a ship’s bow lying on the entrance of a road tunnel. The copper panelled façade resembles the green shade of the water. The public roof of the centre, with its gentle slope, acts as a public piazza.
