On one of the islands, there are several ancient relics, including the 'Mountain of the Nine Immortals', and the Dongshan ancient city, where two famous Ming Dynasty generals, Qi Jiguang and Zheng Chenggong were based. Tongling Town on Northeastern Dongshan Island has an ancient waterside castle. Tonghshan Castle was built of stone in 1387 by Zhou Dexing of the Ming Dynasty to protect against Japanese pirates. The gate tower still stands intact. Inside, a path is linked by corridors and the exquisite Temple of Guan Yu. The entrance to the temple is flanked by ancient houses, the birthplace of Huang Daozhou, an official of the Ming Dynasty. In 1950, at the end of the Chinese Civil War, the island was the scene of fighting between the nationalist Kuomintang and Chinese Communist forces, and again in 1953 during the so-called Dongshan Island Campaign, an unsuccessful attempt by the nationalists to retake the island.
