Atlas Obscura is one of the largest, most well-known and most impeccably awesome archives of amazing places, foods and experiences in the world.
Here is their list of places to see in Denmark! From Copenhagen's most celebrated theme park and gardens, to the sculpture that's the de facto symbol of Denmark, to a vortex-shaped aquarium home to Europe's largest school of piranhas, to a walkable map of the world made by one man, this Nordic country is a wonderland of things to see! How many of these cool spots have you been to?
Note: Some of these you cannot visit or see anymore, which have been marked with (Permanently Closed). So therefore, if you haven't already seen them, I don't know if you'll ever be able to completely finish this list.
Note 2: This is as of July 5, 2024. Sorry future people, there will definitely be more that can't be added.
