It was first built in the Tang Dynasty and rebuilt in the third year of Yuan Zhizheng (1343). It covers an area of 4 acres and has a construction area of 100 square meters. Wenchang Pavilion, the only remaining cultural relic of the Yuan Dynasty, is an all-wood structure. Its architectural style is a single eaves gable roof covered with cloth tube tiles. It is 3 rooms wide, with obvious eaves columns and side legs. Six bunks are laid out under the front eaves to form brackets. Double arch: The first arch with melon seeds is carved in the shape of a wing, and the second arch with sloping arches on the left and right is extremely unique. The brackets are made of thick materials, the beams are small in lift and fold, and the roof is flat. The four eaves columns are made of larger materials. The entire building not only has some of the architectural features in the Song Dynasty's "Building French Style", but also has obvious local characteristics.
