Also known as: Sendai-jou (仙台城), Gojourou (五城楼)
Lit. 'Fresh Leaves Castle Ruins'
The castle sat on Aoba Hill and was naturally defended by a 400-foot cliff on one side and the Hirose River on the other. Masamune built the Inner Citadel and the Western Wing on Aoba Hill, and Date Tadamune built the Second Wing and Third (Northern) wings at its base. The ruins of the Third Wing is now the Sendai Museum.
All that remains of the original castle today are old stone walls; the rest were dismantled or destroyed in fire, earthquakes, and bombings.
