Setting

Set in the mid-1990s, Digital Fortress unfolds primarily within the high-tech confines of the National Security Agency (NSA) headquarters in Fort Meade, Maryland. This secretive facility serves as the epicenter for the agency's code-breaking operations, housing the formidable TRANSLTR supercomputer that forms a crucial backdrop for the novel's events.

While much of the action takes place within the NSA's fortified walls, the narrative expands to include international locales. A significant portion of the story unfolds in Seville, Spain, where the protagonist David Becker embarks on a perilous quest. The ancient city's winding streets, bustling plazas, and historic cathedrals provide a stark contrast to the sterile, high-tech environment of the NSA.

The novel also touches on other global settings, including brief mentions of Tokyo's towering skyscrapers. These diverse locations underscore the worldwide implications of the cryptographic battle at the heart of the story, reflecting the interconnected nature of global security in the digital age.
