St. Louis travel tips
1) Do you know what a Climatron is? Visit the world's first air-conditioned greenhouse in St. Louis | The Missouri Botanical Gardens in St. Louis houses the climatron, the world's first greenhouse filled with conditioned air. It is covered with a geodesic dome enclosed in rigid plexiglass panels. Sophisticated climate control systems create rainforest conditions under the dome. More than 400 species of plants grow inside. The unusual look of the building and the full feeling of being in the rainforest have made this place very popular with tourists and locals alike. |
