Zhongshan Square (simplified Chinese: 中山广场; traditional Chinese: 中山廣場; pinyin: Zhōngshān Guǎngchǎng) is a city square in the Zhongshan District of Dalian, Liaoning, China named for Sun Yat-sen (popularly known as Sun Zhongshan); originally designed and built by the Russians in the 19th century.
The square was originally built in 1898 as Nikolayevskaya Square (Russian: Николаевская площадь, 'Nicholas II's plaza'), when the Russian Empire controlled Dalian (the then Port Arthur).
Inside the five-lane roundabout there is a green zone and a paved area where people gather to dance on summer evenings, participate in foreign language corners, or do other activities.
There are pedestrian underpasses leading to the inside of the square from both the Zhongshan and Renmin roads.
The ten roads that radiate from the square in clockwise order are: The Renmin and Zhangshan roads make up the main east-west artery of the downtown Dalian area.
