Citadel
Ken Griffin's firm
A citadel is a fortress, typically one commanding a city from high ground.
The word suggests a stronghold of last defense—where defenders retreat when outer walls fall.
Figuratively, citadel describes any bastion of power or principle: a citadel of free speech, the last citadel of the old regime.
The financial firm Citadel has made the word familiar in market discussions.
