Baimiweng Fortress, also known as Dutch Fortress, is located on the west bank of Keelung Harbor. It is a municipal historical site and together with the fortress on the east bank, it guards the harbor. Legend has it that the Spanish and Dutch built a castle here. The fortress was built during the Sino-French War, but the current buildings should be the result of the Japanese army's reconstruction during the Japanese occupation in response to the Russo-Japanese War. It has played a pivotal role in various foreign wars since the Qing Dynasty.
The ruins are relatively well-preserved, containing a pottery emplacement area, ammunition depot, observation post, and machine gun emplacements. The command post was located on a small hill to the west of the gun emplacements, while the observation platform was situated on the hilltop to the right. The four gun emplacements were arranged in a long, straight line, forming the first line of defense against the enemy and one of the most distinctive features of the Baimiweng Fort. Since the primary mission of the Baimiweng Fort was to directly destroy enemy ships overseas with powerful firepower, this linear configuration facilitated command and control. Of the four original cannons in the expansive gun emplacements, only one remains; the Armstrong breech-loading cannon currently in service in the park is one of them.
Furthermore, the Baimiweng Fort offers a panoramic view of Keelung Harbor, overlooking the vast expanse of the harbor. With its towering waves and the three large smokestacks of the Xiehe Power Plant, it has become a landmark of Keelung Harbor. It has also attracted popular TV dramas for filming, and many tourists make a special trip here. Gazing at the sea from here is a soothing and relaxing experience, making it a great place for sightseeing and leisure. Especially in summer evenings, one can enjoy the harbor lights, a starry sky, and a gentle breeze.
