Built in 1009, it is the only brick tower confirmed as a construction of the early Northern Song Dynasty (960-1127) in Guangdong Province. Shaped like a hexagon, the tower has nine stories and a height of 42.5 meters. Its construction style imitates that of a pavilion, with its six eaves holding up the spire. A side door surrounded by railings is located on every floor. Brick dougongs (a system of bracketing in Chinese construction where wooden square blocks are inserted between the top of a column and a crossbeam) were built in a simple yet powerful style. The iron-cast tower comprises a canopy, a vase, a nine-layered wheel and a pearl. Steps inside the tower lead to the top, which overlooks the entire county.
