Ahou is Pingtung City’s former name and was built in 1836 (16th year of Emperor Dao-Guang’s reign in Ching Dynasty) with funds donated by local gentries in fear of bandits which could threaten the lives of the city residents. Because Ahou City was not under the jurisdiction of the government at the time, therefore its history was not documented in the Gazetteer of Fengshan County with only a brief description inscribed on the city gate entrance tablet.Ahou City used to have 4 gates each located at North, South, East and West. However, due to the lack of maintenance in addition to road reconstruction during the Japanese Occupation Era, most of the walls were removed with only an opening of the East Gate remained. Known as today’s “Zhaoyan Gate” situated beside Jhongshan Park, the East Gate is now listed as 3rd Category Historical Site by the Taiwanese government.Zhaoyang Gate is approximately 3.6m in height with upper half built with bricks to give its petruding shape; openings in the lower half are symmetrical brick arch with sides of the opening constructed with cobble stones; above the front gate is a horizontal tablet with “Zhaoyang Gate” inscribed along with 17 battlements made of bricks with an estimated year of construction expansion around 1976.Ahou City Gate is a 3-sector construct with its front and back sector built with long bricks in the shape of an arc. A rectangular opening is located in center of the arc. The Gate wall was built with basaltic granite with its corners composed of simple brick columns. In addition, an arced opening was also built with red bricks in the center. Arc diameter consisted of 3 different sizes with tenon holes for door bar insertions were embedded on both sides of the wall.Although today Ahou Gate today is a worn-out gate with faded glamour with mottled bricks and weeds growing at the base, it still displays a strong ancient ambience when compared to the modern park adjacent to it.
