citadel
Fortified city center
A citadel is a fortress, typically one commanding a city from high ground.
The word suggests a stronghold of last defense—the place you retreat to when outer walls have fallen.
Figuratively, citadel describes any bastion of power or principle: a citadel of democracy, the last citadel of resistance.
