Here Are The Hidden Locations Of Zelda: Breath Of The Wild's Memories
The Legend of Zelda: Breath of the Wild's story is completely optional, but it's a good one worth seeking out. You will encounter a number of story moments by simply pursuing the dungeons and following the main path, but for the complete picture, you will need to find a number of hidden cutscenes throughout the land of Hyrule. You won't see any of those cutscenes below, but it's not a bad idea for me to include a spoiler warning here, just in case.
Below you will find the reference picture for each of the story moments, a larger map picture, a zoomed in map picture, and a picture of exactly where the moment is.
Sacred Ground Ruins
Kara Kara Bazaar
Spring of Power
Sanadin Park Ruins
Lanayru Road - East Gate
The final story moment is a little bit different, and demands you recover the first 12 moments before you can go after it.
