How did Plato describe the lost city of atlantis?

Plato described Atlantis in his dialogues "Timaeus" and "Critias" as a powerful and advanced civilization that existed around 9,000 years before his time. He depicted it as an island located beyond the "Pillars of Hercules" (the Strait of Gibraltar), characterized by its rich resources, impressive architecture, and sophisticated society. Atlantis was said to be larger than Libya and Asia combined, but it ultimately fell out of favor with the gods due to its hubris and moral decline, leading to its catastrophic demise.
