Bloody ceiling: Over 1000 men died under Mototada TORII while defending the castle during the Siege of Fushimi, a conflict which is said to have led to the Battle of Sekigahara, and the floorboards from the corridor in which the remaining men committed suicide were made into this ceiling to serve as a memorial on which fresh-looking bloodstains can still be seen.
血天井－関ヶ原の戦いの前哨戦ともいわれる伏見城攻防戦で鳥居元忠以下1000人余りが城を死守し，最後に自刃した廊下の板の間を供養のために天井としたもので、今も生々しい血の痕があちこちに残る。
