You can visit the actual cheeseburger or watch it via webcam.
Six years ago, McDonald's sold its very last cheeseburger in Iceland. The economic downturn pushed the fast food chain out of the country, but there's still proof that it once existed. The evidence is a six-year-old cheeseburger in a cloche at Bus Hostel Reykjavik and it doesn't look a day older than the day it was made. (For the record, McDonald's cheeseburgers are known for not rotting, but this takes it to a new level.) Even if you can't make it to Iceland, you can take the display in via live webcam (seriously).
The burger was first purchased by Hjörtur Smárason in October 2009 and sat in his garage up until 2014 when he decided to donate it to a local museum. Somehow, it ended up at Bus Hostel and is undoubtedly one of the strangest tourist attractions around.
