If you find chess interesting then at least for someone from the US or Western Europe the match between Fischer and Spassky was an international event serving as yet another proxy fight (sports, space race, etc.). The museum does a good job including a video about the match. The guide I had (unfortunately, I cannot remember her name) was excellent and took lots of time to walk a small group of us through the museum. She was actually even one of the reasons the museum was placed in Selfoss. Watch the documentary, look at the various cartoons and newspaper articles. It's quite interesting, as is the story of the Fischer-Spassky rematch and the political intrigues leading to Fischer's imprisonment in Japan before he was made an Icelandic citizen. Fischer was flown out and spent the rest of his life in Iceland. He is buried nearby in Selfoss at a small church.
