城塞 (jōsai) specifically implies a fortress within or commanding a city, matching 'citadel' closely. 要塞 (yōsai) is a broader term for any fortress or stronghold, often military. 城 (shiro) means 'castle' and is appropriate when the citadel is a castle-like structure, common in Japanese history.
When 'citadel' is used figuratively (e.g., 'citadel of capitalism'), direct translation as 城塞 may sound odd. Use 牙城 or 砦 for a more natural figurative expression.
