The Han Chinese settlement “Heliaogang Jie” (today's Zhongyi Rd) later crossed the main street of Provintia and formed the so-called "Shizi Dajie" (十字大街) or The Great Cross Street. With the fall of the Ming dynasty, new migrants flooded into the settlement. Chinese population boomed from 5,000 to 35,000 between 1640 and 1661. As a result, farmers, deer hunters, traders and craftsmen each formed a colony on the cross street. Due to the Chinese tradition where different trades and regions worship different Taoist gods, the city later developed into neighborhoods, each with own center temple. Now, after 300 years of Chinese migration, the city has become a showcase of both Taoist and Chinese Buddhist temples. Although the city has transformed dramatically since the late 19th century, the temples remain because of their importance to the locals. Some of the early administration centers have also been transformed into temples for political and social reasons. An administrative building of the Tungning Kingdom became temple of the sea goddess, and the location where Tungning Kingdom performed annual ceremonies of prayer to Heaven is now the Altar of Heaven Temple. Castle Provintia, one of two Dutch forts in Tainan, now has a sea god temple and a literacy god temple built on top of it, creating East-West fusion architecture. Many Han Chinese religious and historic monuments can be found near the old cross street centered by the Castle Provintia. The cityscape of modern Tainan was founded under the urban redevelopment programs carried out by Japanese colonial government. The city center adopted a Baroque design similar to the Paris renovation in mid 19th century, the plan connected major facilities via a system of wide streets and five square-roundabouts. Among the five squares, at the center is the most important crossing point. The square is surrounded by the city hall, the fire brigade and the weather bureau. It is connected by a number of avenues heading towards the train station, the airport, military bases and the dock at the end of the Anping cannel. With the police station and the court nearby, this area demonstrated the power of the colonial government within the city. The financial district was located in and between Taishō park and Anping cannel along , the modern day Zhongzheng Rd. It was the busiest street of the city from Japanese rule to the mid-1990s. Many Colonial Baroque style historic buildings from Japanese era can be found in this part of the city.
