Suogang Towers include the North Tower and South Tower. They are both around three stories in height, situated in the north of the old settlement. They were built actually for the sake of "Feng Shui," an ancient Chinese belief that the way architecture is built and the way objects are arranged affect people's life, health, and success. How so? At the place where the towers are located used to be a hill which is believed to make good "Feng Shui." However, the hill gradually disappeared because of strong northeast monsoons. In order to make up the loss, two stone towers were built. There was an old local saying which depicts the phenomenon of aeolian erosion "Suoguangang (now called "Suogang") lost a hill, and Zhumushui (now called "Shanshui") lost a bay," describing that the hill was blown into the bay. Suogang Towers are nine-level stone cairns. Among all the stone cairns in Penghu they are the oldest examples of their kind. Originally built from black rocks, they were rebuilt in 1962 with black rocks and concrete. The towers were originally seven levels with the first level covering 66 square meters, but in 1962 they became nine levels after restoration, and are now the highest stone towers in Penghu (around 14 meters high).
