203 Hill, Strategic hill in Lushunkou District, Dalian, China

203 Hill is an elevation in Lushunkou District in Dalian that rises 203 meters above sea level. From its summit, the view extends over the Yellow Sea to the south and forested slopes to the north, while landscaped gardens surround the top.

Russian troops fortified the hill during the Siege of Port Arthur between 1904 and 1905 because it offered a clear view of the harbor. Japanese forces captured the position after several assaults, marking the turning point of the siege.

The name comes from the hill's height of 203 metres. Nogi Maresuke rendered "203" as 爾霊山 (Nireisan, "mountain awaiting your spirit") in a Chinese poem, and his calligraphy of those characters appears on the summit memorial tower. A stone monument marks where his son Yasusuke fell on the Bohai-facing slope.

The hill lies in Lushunkou District, Dalian, and was closed to foreigners as a naval base area until part of the zone including 203 Hill opened in July 1996. The summit carries a memorial tower inscribed with the characters 爾霊山 in Nogi Maresuke's own hand. The cherry garden at the foot of the south slope, planted from 1993 onward, peaks in late April.

Nogi Maresuke's second son, Yasusuke, died in the fighting here, and a stone monument marks the spot on the slope facing the Bohai Sea. Nogi's Chinese poem renamed 203 as Erlingshan, "mountain awaiting your spirits", and his own calligraphy of those characters stands on the summit memorial tower.
