Anping Castle is located in Tainan and is an ancient castle in Taiwan. Every sunset at dusk has a beautiful scenery. In 1624, the Dutch ruled Taiwan and built the "Herland of the City" in Anping, which is now the Anping Castle. After Zheng successfully expelled the Dutch, he changed the castle to a city and renamed it "Anping Town". After the Qing Dynasty, he changed to the military uniform bureau. In the same year, the British army committed a crime. The guns hit the arsenal in the city and caused an explosion. The city wall was Destroyed and turned into ruins. Although it has been built many times, it is no longer magnificent in the past, but the rich historical materials and cultural significance of the preservation are still very worthwhile.
