From Wikipedia: The Muttart Conservatory is a botanical garden located in the North Saskatchewan river valley, across from downtown Edmonton. The conservatory consists of four glass, pyramid-shaped structures that showcase plants from arid, tropical, and temperate climates, providing a welcome oasis of warmth during winter. The fourth pyramid hosts a theme that changes throughout the year.
