@DavidBrown This is basically the botanical section of Calgary Zoo. There are some nicely landscaped gardens around the structure, with an entrance area/ballroom that is frequently used for special events and weddings. There are another two sections: one side is hot, humid and teeming with butterflies amidst the thick foliage, while the other side also has plenty of plant life but no butterflies. The zoo's grounds are an absolute delight for horticulturists, with lots of flower beds and nicely designed layouts along the pathways and exhibits. The Enmax Conservatory (sponsored by an Alberta energy company) is gorgeous and well looked after, but so is the rest of the zoo.
