Zhongshan Square (simplified Chinese: 中山广场; traditional Chinese: 中山廣場; pinyin: Zhōngshān Guǎngchǎng) in Dalian, Liaoning, China, was originally designed by Russians in the 19th century. Several classical buildings located on the square were built during the first half of the 20th century by the Japanese.
The square was originally built in 1898 by the Russians as Nikolayevskaya Square (in Russian: Николаевская площадь, meaning Nikolai's plaza). It was later renamed by the Japanese as Ōhiroba (Japanese: 大広場), meaning large plaza as compared to the smaller Nishihiroba (Japanese: 西広場) meaning west square), now called Friendship Square (simplified Chinese: 友好广场; traditional Chinese: 友好廣場). After 1945, it was once more renamed as Zhongshan Square, in honor of Sun Zhongshan (Sun Yat-sen), the first president of the Republic of China.
Zhongshan Square is 213 metres (699 ft) in diameter. 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 things. There are underground passages leading to the inside of the square from both Zhongshan and Renmin Roads.
