What is Impel Down
Impel Down is depicted as a maximum-security prison directly controlled by the World Government. Built deep beneath the sea, it resembles an impregnable fortress. The deeper the levels go, the more dangerous the prisoners confined there become. With fearsome jailers and monstrous beasts maintaining security, it is renowned as an “inescapable prison.”
In the story, Luffy infiltrates Impel Down to rescue his brother Ace, facing powerful enemies and forming uneasy alliances along the way. The events in Impel Down serve as a turning point that leads directly to the Marineford War. Thus, Impel Down is not only a stage for action but also a key element that shifts the fate of the characters and the entire story.
The History of Castel Sant’Angelo
Castel Sant’Angelo was built in the 2nd century AD by Emperor Hadrian as his own mausoleum. Over the centuries, it transformed into a fortress, prison, and refuge during wars and political upheavals. During the Middle Ages, it also served as a papal refuge and became a crucial part of Rome’s defenses.
Its history as a prison strongly resonates with the imagery of Impel Down. The thick stone walls, closed architecture, and isolation from the outside world created a sense of hopelessness for inmates. These elements are mirrored in the manga, giving depth and authenticity to the fictional setting.
