Step back in time at Hiroshima Castle, a faithful reconstruction of the 16th-century fortress that once stood here. While the original was lost to history, this beautiful keep, often called 'Carp Castle,' stands as a powerful symbol of our city's resilience. You can wander the peaceful grounds for free, but for a small fee, the five-story tower offers a fascinating museum detailing Hiroshima's past and incredible panoramic views of the modern city from the top. It's a serene escape in the heart of the city, with plenty to explore within the moat-lined walls, including a shrine and original foundation stones.
