NEMO Science Museum is a science centre in Amsterdam, located at the Oosterdok. It was built on top of the IJ-tunnel that connects the centre of Amsterdam with the north of the city. The striking building, designed by Italian architect and engineer, Renzo Piano, opened its doors in 1997. Some say the shape of the building mimics the appearance of a large boat, but others suggest that it's actually a reflection of the tunnel it was built upon.
