This particular part of the Royal Ontario Museum is an extension completed in 2007 and looks almost like crystals coming out of the back of a building. This building is probably my favorite that I’ve seen of Libeskind’s work so far, simply because of how the exterior blends so well together even though it is compromised of two entirely different structural types. The Crystal structure was apparently one of the most complicated projects in North America at the time, and involved lots of different strategies to be able to build it and have it be a stable structure.
