Considered one of Japans Oldest “original” construction material Castle, Hikone Castle is located in Hikone, Japan. Constructed in 1603 by The Li Clan (local Daimyo), it was a central Keep structure consisting of 4 floors. Set on a 75-foot foundation mound, it also featured a defensive Perimeter wall (now extinct). In 1868, an Emperor Order decreed that all Regional Castles and Fortifications be dismantled. Hikone was spared by The Emperor. Although renovation has been down to preserve the structure, Hikone still contains much of it's original construction and materials.
