Hiroshima Peace Memorial Museum

Hiroshima's Peace Memorial Park (平和記念公園, Heiwa Kinen Kōen) is one of the most prominent features of the city. Even visitors not looking for it will likely stumble upon the large park of over 120,000 square meters. Its trees, lawns, and walking paths are in stark contrast to the surrounding downtown area. Before the bomb, the area of what is now the Peace Park was the political and commercial heart of the city. For this reason, it was chosen as the pilot's target. Four years to the day after the bomb was dropped, it was decided that the area would not be redeveloped but instead devoted to peace memorial facilities.

Hiroshima Castle

Hiroshima Castle (広島城, Hiroshimajō), also called the Carp Castle, is a good example of a castle built on a plain in the center of a city as opposed to hilltop and mountaintop castles. Its main keep is five stories tall, and its grounds are surrounded by a moat. Also within the castle's precincts are a shrine, some ruins and a few reconstructed buildings of the Ninomaru (second circle of defense). Hiroshima developed as a castle town, whereby the castle was both the physical and economical center of the city. Built in 1589 by the powerful feudal lord Mori Terumoto, Hiroshima Castle was an important seat of power in Western Japan. While it was spared the demolishment that many other castles met during the Meiji Restoration, like the rest of the city, Hiroshima Castle was destroyed by the atomic bomb in 1945.
