The "Crystal Palace" is composed of five interconnected and self-supporting prismatic structures, basically without a positive angle. The sloping walls form a unique large-volume internal space. The cross-shaped corridor passes through the mourning hall in the middle, and the bright windows fill the room with natural light, adding a strange scenery to the city. The new annex is the main part of the museum's $250 million reconstruction and expansion project, which will be completed in 2009.
After the expansion was partially opened, it became the object of people's pursuit. Although the Denver Art Museum and ROM are 1500 miles apart, both buildings have liebeskind's iconic angular aesthetics and crystal modeling. And there are buildings like bows, holding their heads high above public spaces. The humanities museum on the third floor includes Egyptian, Greek and Ida Larrea, Islamic, Roman, military weapons from the Bronze Age to World War I, artistic decoration products popular in France in the 1920s and 1930s, Jewish life in Europe and North America in the 20th century, the evolution of decorative art from the Middle Ages to the 20th century, glass crafts and drawings and models of the new Royal Ontario Museum to be built soon.
The museum also houses Egyptian cultural relics (such as mummies), minerals and spectacular vertebrate fossils (such as dinosaur fossils). In addition, there is a bird museum, and a wide variety of bird specimens are placed in the drawer in order.
