In the early days of Cijin's development, military affairs were very important, and a fort was built a fort at the peak of Cihou Mountain in the Kangxi Emperor's reign, mainly in order to defend Kaohsiung Harbor. Most structures in the fort were built with red tiles, and are imbued with traditional Chinese style. If you come to side walls and doors (bazimen and baziqian), the four characters in Chinese “ Zhen Zhen Tian Nan” are still visible – the fort has an extraordinary atmosphere. Pairs of characters have been inscribed on the walls, accompanied by inscriptions of bats in the corners, and many traditional architectural patterns can be seen on the ramparts and stairs, all of which are symbols of Chinese style.
