Vegetarianism seems like it's everywhere these days. And why not? Studies show that vegetarianism—even partially—can help prevent heart disease, help the environment and even help you lose weight.
Still, forgoing meats for veggies is a relatively new phenomenon, but did you know that vegetarians have actually existed for quite some time?
Over 100 years ago, before vegetarianism was even a word, the world's first still-operational vegetarian restaurant, Hiltl, opened in Zurich. You can still visit today!
Check out the slideshow above for more about the world's only operational vegetarian institution from the 1900s.
