The new castle was named Aoba, after the name of the Aobayama mountain. It featured strong fortifications, but its main keep was never finished. The castle was dismantled, like many other castles, at the beginning of the Meiji period.
Today the site of the Aoba castle is marked by the stones of the old walls of the palace and by an equestrian statue of Date Masamune.
