Remain of the formerly East Gate of the Tainan Prefectural City Wall(原臺灣府城東門段城垣殘蹟)
Based on the structure and appearance, the ruin of the city wall located between Da Dongmen (grand east gatehouse) and Xiao Dongmen (minor east gatehouse) in Guanghua Street should have built in 1788, the same year of the Xiao Dongmen ruin in the Guangfu Campus of National Cheng Kung University. After the Zhu Yigui armed rebellion, the Qing government built the wooden barrier city in 1733. After the Lin Shuangwen rebellion in 1788, the Qing government replaced the wooden barrier to mud barrier to fortify defense with stronger and larger fortifications.
