Facebook story is a nice feature introduced by Facebook that appears at the top of your news feed. The story appears only for 24 hours before it vanishes away, but the good news is you can save the story of your friends in your story archive.
Your archive can be turned on or off. If your story archive is turned on, your photos and videos will be archived when they disappear from your story after 24hours automatically. Also, remember you are the only one that can see your story archive. Read below to see where you can find this option.
Where to find story archive on Facebook
Login to your Facebook account, in your news feed, click on your name which will take you to your profile.
