Learn about the remarkable feats of engineering behind the Canal Ring through this museum's holograms, videos, models, cartoons, scale model of Amsterdam and other innovative exhibits, which explain how the canals and the houses that line them were built. Unlike at most Amsterdam museums, you can't simply wander through: small groups go in together to experience the multimedia exhibits. It takes about 45 minutes, and you'll come out knowing why Amsterdam's houses tilt. Admission includes an audioguide.
