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 Argentina! From a historic palatial theater now one of the world's most beautiful bookstores, to a bright little alley that's a part of tango history, to the beautiful inspiration for the Patagonia logo, to a tower modeled after the Divine Comedy, the 8th-largest country is a wonderful place full of wonderful places! How many of these awesome sites 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 May 11, 2024. Sorry future people, there will definitely be more that can't be added.
