Renzo Piano designed the NEMO Science Center located in Amsterdam. This building is one of the most unique buildings I have ever seen. It is a giant copper-green shape that looks to be arising out of the water. This building is located on top of a tunnel, which proved to be challenging to Renzo, but he took that tunnel as inspiration for the shape of this building. This building looks very out of place to me. There is a roof-terrace (pictured below) that overlooks the city however, and this building seems like a unique place to visit.
