Aoba Castle was built in 1600 by the powerful feudal lord Date Masamune. Because of considerations for the castle’s defense, Masamune chose to locate his fortifications on Mount Aoba, 100 meters above the town below.
In the last 400 years the castle endured the anti-feudal fervor of the Meiji Period, a giant fire in 1882 and the carpet bombing of 1945. Now all that is left of the castle are remnants of the outer stone walls and a guard tower. The location’s lookout onto the city below presently serves an aesthetic rather than military role, though a statue of Masamune, armor-clad and horseback, recalls the site’s origins.
A museum commemorating Aoba Castle’s history can be viewed on the site. It features models of the castle as it stood in the Edo Period, artifacts from the castle, and a theater that shows a short movie, in Japanese, on the castle.
