The Xiabanquan Beacon Tower, historically known as the "Xiabanqiao Tower", is located inside the Banquan Sports Park. It serves as a road pier in the defense system of the Great Wall in the Ming Dynasty. It is situated about five kilometers away from Yanqing City next to the "Banquan Path", a road heading toward the ancient northwestern silk road, guarding "Banqiao". The beacon tower is tall and large, and has a stone base, a rammed earth core, and a brick exterior. It is divided into upper and lower floors. There is an arch gate in the east of the building, with a passage to the roof. There are watchtowers on the upper floor, surrounded by crenels. The tower is surrounded by walls. The barracks are equipped with gates and wells, which are used for defense and intelligence information communication. Together with the Shangbanqiao Tower and Zhangshanying Tower, it constitutes the military information communication and defense system in the northwest direction of Yanqing City.
