The Royal Ontario Museum - TORONTO, CANADA

The Royal Ontario Museum is a museum of art, world culture and natural history in Toronto, Ontario, Canada. It is one of the largest museums in North America and the largest in Canada and it is Canada's largest field-research institution, with research and conservation activities around the world. 

With more than 6,000,000 items and 40 galleries, the museum's diverse collections of world cultre and natural history contribute to its international reputation. 

The extension to the Royal Ontario Museum (ROM), now named the Michal Lee-Chin Crystal, presented a unique challenge to build and was among the most complicated construction projects in North America. There are no right angles and only one vertical wall in the structure - the five crystals are designed as interlocking self-supported structures.
