203 Hill is a high ground located in Lushunkou District, Dalian, Liaoning Province, China. In 1904-1905, one of the fiercest battles was fought between the Japanese and Russian armies in the Siege of Port Arthur, during the Russo-Japanese War.
It is so named because it is 203 metres above sea level.
Maresuke Nogi after the battle used the same Chinese pronunciation to name it "Thee-Spirits Mountain" in his famous poem:
