Located in the old city of Stockholm, the capital of Sweden, the Nobel Museum was built 100 years ago when the Nobel Prize was awarded in 2001. Its predecessor was Sweden's ancient stock exchange. In front of the Nobel Museum, there is an ancient well in the central square of the old city. Hundreds of years ago, it was the only well in this area for residents to drink. It is said that Nobel grew up drinking the spring water flowing from this well.
