Ruins of Ninomaru of Hiroshima Castle

While the main keep of Hiroshima Castle is a concrete reconstruction, the Ninomaru (second bailiwick) features meticulously restored wooden interiors built using traditional, nail-free Edo-period techniques. Visitors can walk through the connected drum tower and turrets, which offer a much more authentic architectural experience than the main tower. It is a peaceful, less-crowded spot that provides deep insight into feudal defense design.
