Hiroshima Castle, Japan:

Hiroshima Castle, sometimes called Carp  was a castle in Hiroshima, Japan which was the home of the daimyō of the Hiroshima han. The castle was constructed in the 1590s, but was briefly destroyed by the atomic bombing on 6 August 1945. It was rebuilt in 1958, a replica of the original which now serves as a museum of Hiroshima's history prior to World War II.Mōri Terumoto, one of Toyotomi Hideyoshi's council of Five Elders, established Hiroshima castle in 1589 at the delta of the Otagawa river. There was no Hiroshima city or town at the time, and the area was called Gokamura, meaning 'five villages.' Beginning in 1591, Mōri governed nine provinces from this castle, including much of what is now Shimane, Yamaguchi, Tottori, Okayama and Hiroshima Prefectures.When construction on the castle began, Gokamura was renamed Hiroshima, as a more impressive name was called for. "Hiro" was taken from Ōe no Hiromoto, an ancestor of the Mōri family, and "Shima" was taken from Fukushima Motonaga who helped Mōri Terumoto choose the castle site. Some accounts state that the name 'Hiroshima', meaning literally 'wide island', comes from the existence of several large islands in the delta of the Otagawa, near the castle's site.Following the battle of Sekigahara in 1600, Mōri was forced out of the castle, retreating to Hagi in today's Yamaguchi prefecture. Fukushima Masanori became the lord of Aki and Bingo provinces. However, the new Tokugawa shogunate forbade any castle construction without permission from Edo; this was part of how the shogunate kept the daimyō from gaining power and overthrowing the shogunate. When Fukushima repaired the castle following a flood in 1619, he was dispatched to Kawanakajima in today's Nagano prefecture. Asano Nagaakira became lord of the castle.From 1619 until the abolition of the feudal system during the Meiji Restoration (1869), the Asano family were lords of Aki and Bingo provinces.After the Meiji Restoration, the castle came to serve as a military facility, and the Imperial General Headquarters was based there during the First Sino-Japanese War in 1894-1895. The foundations of several of the GHQ outbuildings, just a few hundred paces from the castle's main tower, remain today.The castle was destroyed in the atomic bomb blast of August 6, 1945. For many years, it was believed the castle structure was blown away by the explosion that destroyed Hiroshima, but newly discovered evidence suggests the explosion only destroyed the lower pillars of the castle, and the rest of it collapsed as a result.The present tower, constructed largely of concrete, was completed in 1958.
