This gained popularity a year or two ago when a few youtubers took it upon themselves to determine that if Atlantis were real, what geological features might be the most likely candidates? Ancient Architects and Bright Insight both come to mind, here, with the latter choosing the Richat Structure as their target of interest and Ancient Architects chosing Rockall.
However it may be appealing to suggest that it fits Plato's description, the Richat structure is almost certainly just the remains of a fantastically enormous geologic dome that grew and shrank repeatedly over eons; causing the ring structures to form from the expected natural sedimentation and similar.
Still absolutely wild to consider, given its size.
That's actually not out of line with what Ancient Architects proposed; the operator of that channel tries to shy away from pure speculation, and proposed sea level rise as a cause for Atlantis sinking; and from there, they narrowed in on Rockall, which has interesting now-sunk but previously above-water features.
Cool theory never heard of it before. Though the only description we have say Atlantis sank in single day and night of misfortune. Doesn't really fit sea level rise. Though that could just be poetic.
This is just as much speculation as it is to claim that it's truly the site of Atlantis. I'm siding with the YouTubers ;)
In any case, would love to see an unbiased archeological dig there. From what I recall watching videos about this place, there are some political/legal challenges to gaining access there besides for individual travel.
