Mudou Islet Introduction
Mudu Islet is located 7 kilometers away from the southern Ji Bei Islet. The island has a circumference of 843 meters and an area of only 0.0244 square kilometers, making it a mini island. It is well-known for the Mudu Islet Lighthouse, and apart from the lighthouse staff, there are no other inhabitants on the island. Mudu Islet is situated to the north of Ji Bei Islet and is the northernmost island in the Penghu archipelago. It gets its name from its shape, which resembles a human eye. Another theory suggests that due to the island being formed from basaltic flat-topped hills, its shape also resembles a chalk line used by carpenters, hence the early name "墨斗嶼" (Mok Dou Yu), which later changed to "目斗嶼" (Mudu Islet) due to phonetic variations. Additionally, being at the northernmost point of the Penghu archipelago, it is also referred to as "北島" (Northern Island). There are many reefs nearby, and shipwrecks occurred frequently in the past, which led to the establishment of the Mudu Islet Lighthouse during the Guangxu era of the Qing Dynasty to guide ships, and it has been over a century since its construction. The Mudu Islet Lighthouse stands at a height of 40 meters, with its black and white tower rising majestically from the dark brown reefs. It was the first lighthouse built in the Penghu archipelago after the Japanese took control of Taiwan. The lighthouse stands at 39.9 meters, making it the tallest cast-iron lighthouse in Taiwan and also the tallest cast-iron lighthouse in the Far East (the only inhabitants are the lighthouse keepers). The water intake is located inside the lighthouse, directing rainwater collected from the lighthouse and dormitory roofs directly into the tower, making it the only lighthouse in Taiwan to have a water intake located inside the tower. Currently, there is no electricity on the island; power is generated entirely by three generators for the operation of the lighthouse. The Mudu Islet Lighthouse was selected as one of the top ten historical buildings in Penghu County during a voting event in 2001!
