The gate's defensive role ended in 1895. When the Japanese advanced on Tainan from three sides, their troops entered the city through the Small South Gate on October 22. After that, the city walls began to be torn down, and the gates decayed from neglect. The outer barbican gate here collapsed. By 1917 the walls had almost entirely disappeared, and only four gates survive in Tainan today: the Yuedui Gate, the Great East Gate, the Great South Gate and the Small West Gate. The gate itself was repaired in 1927, partly using materials from the demolished East Guo Gate, and two years later the area became Nanmen Park. In 1935, for the Taiwan Exposition, 45 old steles were gathered and displayed here, including nine from the shrine of Fukang'an, which is why a stele forest stands in the park today. That same year the gate was designated a historic site under the name Tainan Castle. Back in 1925, plans to build a park and relocate nearby graves had met strong protests from local gentry and intellectuals. Then came nature. On the morning of July 18, 1963, Typhoon Wendy brought the tower down at 6:40, injuring two people. By 1967 only the gate passage was left. The city rebuilt the tower in 1975, and in 1977, as part of a plan to restore historic sites for the Tainan tourism year, the gate was rebuilt in its original form. It is now the largest surviving city gate tower in Taiwan. Because it stands right beside Jianxing Junior High School, graduating students walk out through the gate after their ceremony, a symbolic step into the next stage of life.
