Shiro

Shiro is the Rokugani word for Castles.

Appearance
Like the kyuden, a shiro was frequently the ancestral estate of a great family, but they were designed placing far more emphasis on function than on form. These military, defensible fortifications were frequently found near to a clan's borders, having expansive storehouses in the event of a siege. Shiro included many "murder holes," openings in the walls from which archers and shugenja could strike down their assailants.
