Kuiwen Pagoda, commonly known as Longtan Pagoda, was built in the Wanli period of the Ming Dynasty (1573- 1620) and was named Stegosaurus. Under the tower is a deep pool formed by the confluence of Xinjiang River and Fengxi River. It is said that the word "Longtan" is engraved on the walls of developed areas of rivers and lakes, so it is nicknamed "See Long Ta".
Kuiwen Tower is octagonal and seven-level, with masonry structure and a height of more than 49 meters. There are doors and windows on each floor, which pass through the internal steps, spiral up, climb up and look out. After the bankruptcy, only the second level is left. In the 19th year of Jiaqing in Qing Dynasty (18 14), the magistrate of a county led Wang and Lai Xun, the magistrate of Shangrao, to rebuild five products. The upper floor is dedicated to the statue of Zitong II Emperor, renamed "Kuiwen Tower". After the reconstruction, it still maintains a simple and solemn architectural style. Although this tower was built in the Ming and Qing Dynasties, its body is intact, retaining the typical shape of brick towers in the Ming Dynasty. The five floors above are covered with lotus petals, bearing the eaves of the tower, which has the taste of Feng Shui Tower in Qing Dynasty. There are stone steps in the tower, which can reach the top and overlook.
There used to be a tower yard under the tower, and there were several buildings in the tower yard, including Chunyang Building, Huiji Women's Temple, Cangjie Temple, Xizi Furnace, Guanshui Pavilion and other ancillary buildings. By the end of the Qing dynasty, these ancillary buildings had fallen down one after another, leaving only precious small stoves.
