Tourists visit the Eternal Golden Castle, alternatively but less well known as Uhrkuenshen Battery, in Tainan, Taiwan, 2015. The castle was built in 1874 and completed on 1876 by the famous Qing official Shen Baozhen in order to safeguard the coast and to defend the island against Japanese invasions. This military facility saw its first action in the Sino-French war of 1884. When Taiwan was ceded to the Empire of Japan by the Qing in 1895, the Taiwanese people fought under the Republic of Formosa banner against the invading Japanese battleships from this fortress. Under Japanese control this military facility lost its value. Its value is completely lost when during the Russo-Japanese War the imperial Japanese government sold some of the fort's cannons.
