Beisi Tower is the best among towers in Suzhou. It is one of the two symbols of ancient Suzhou City, with the other being Yunyan Pagoda on the Tiger Hill. 76 meters high, Beisi Tower is a nine-story construction in octagonal shape, with all its upturned eaves shading the 1.3mu base. Surrounded by fragrant camphor woods, the base is enclosed with low banisters. Along the two sides of the yard are the butterfly-shaped walls. The yard is very attractive with the decoration of ancient trees and rare flowers.
