Two pyramids captured in daylight at Muttart Conservatory
The conservatory's unusual structure, designed by architect Peter Hemingway, is composed of four glassed pyramids built around a central service core. The two larger pyramids are 660 square metres (7,100 sq ft) in area, and the two medium-sized ones are 410 square metres (4,400 sq ft) in size. Three of the pyramids are devoted to displays of plants from the tropical, temperate, and arid regions respectively, the fourth being used for shows that change with the seasons and which feature massed displays of ornamental flowering plants.
