This beacon tower was designed to quickly signal emergencies in the eastern and southern areas of Suwon. A smoke signal from the tower was immediately visible at the Temporary Palace at Hwaseong Fortress, where the local magistrate resided. The tower consists of five chimneys made of brick. Normally, the chimney at the south end was lit in the evening to signal that everything was fine. In case of an emergency, all five chimneys were to be lit. Fortunately, there were no cases in which all five chimneys had to be lit.
