I thought about this before and I got two different theories:

1- There are other places which contain magic in the Land Without Magic. Tamara and Greg said it once to Regina. So, it's logical that Regina kept the underground cave as magical.

2- This is more simple theory. Just because something is not present in our world doesn't mean that it's definetely magical. A dragon may be not magical and live in the Land Without Magic, therefore the underground cave in Storybrooke before the curse is broken.
