Where would they keep dragons at?

There is no evidence to suggest that dragons actually exist, so it is impossible to say for certain where they would be kept. In stories and legends, dragons are often depicted as living in caves, mountains, forests, or other remote and isolated areas. In a more modern context, if dragons were real, they would likely require a large and secure habitat with plenty of space to fly and roam. This could potentially include specially designed enclosures within a wildlife park or conservation center.
