We're taking a break from our usual chronological journey and instead visit a historical site in our own home. In what could be seen as part two of our special episode about dog tags, we continue to look at Sweden's preparations for war in the 20th century. Just like with the dog tags, we found that we're living with a reminder of history, namely a bomb shelter in our own basement! We go to have a look and explore the background as to why there were so many shelters built in Sweden.
