Question 429: Knocking on heaven's door

____X_____ is a term synonymously used to denote something impregnable, invincible and what can only be described as the most secure place on earth. It has been denoted in comics, especially in Donald Duck comics ( read Uncle Scrooge), who compares his fortifications as rivaling ___X___.

Cited in movies such as goldfinger, and shows such as Simpsons, Pinky and the Brain, a slew of movies have used this term to describe the ultimate show of a debaucher's dexterity ( or in layman's terms, a crooks cunning and skill).

But what is unknown to most is that it holds a museum to general Patton, a high school, and has a population of 12000 odd people.
