Lighthouse in Fisherman Island was built in 1778 by the chiefman executive of  Pengfu, Xieweiqi, under the order of Jiangyuansu. This is the first stone lighthouse in Taiwan which is in the seventh level of Chinese Traditional Lighthouse.  In 1828, the lighthouse rebuilt as an octagon stone lighthouse in level seven.  In 1875, it has been re-constructed to be a Western-style, Circular, and ironed lighthouse.  The lamps for the lighthouse are the lens-lamps in Level 4 and white-light lamps of twin light buds lighted up by kerosene. There is a dormitory built for the lighthouse keeper to stay and supervise.   In 1915, the lamps were changed to high-pressure, white Flash Lamp lighted up by fuel gas and were it altered to an incandescent lamp lighted in 1938. In the 55^th year of R.O.C. Era, the lamps were re-quipped as the Level 4 rotatable lens lamps.  In the 70^th of R.O.C. Era, the lamps were increased with two sets of fog signals.

The Lighthouse is located at the highlands of Waian Village with a wide view.  Around the lighthouse is the wall built by laying old stones about 60 centimeters tall. The wall is painted white, the scope now is the same boundary as it in the 11^th year of Tongzhi Period in Ching Dynasty and is shaped as a rectangle.  The length is about 50 meters from east to west and is about 60 meters from south to north with the square measure of approximate 0.3 hectare.  The gate of the lighthouse and its dorms all face southwards.  The whole constructions are divided into the western lighthouse which is rebuilt in the first year of Guangxu Peniod in Ching Dynasty, the dorms located at the north side, and the underground reservoir.  Besides that, there are four dorms, electric machinery room and the warehouse built continuously later.  Inside the lighthouse area is an ancient cracked stele of Fuangxu and a western tombstone built in 1880.  There still are three fog cannons inside the area: big, middle and small.  The big and middle ones are England-made, fore-chest and cast-ironed fog cannons; the small one is German-made hind-chest cannon.  Furthermore, there are two sets of fog-horns to replace the function of fog cannon when the visible scope is shorter than one hundred meters.
