Gangziliao Fort is built in the Ching Dynasty, and it was located at the northeast of Keelung city. This old gun emplacement is as significant as the other gun emplacements considering its history or its architecture. In fact, after World War II, it was still being used as a military facility by the ROC government until a few years ago. This gun emplacement in Sinyi District was ranked to be provincial historic site. During the colonial period, the gun emplacement was renovated and garrison was placed here after Taiwan was returned to China. Then it was abandoned for a long time. Fortunately, the remains of the gun emplacement are well-kept. Walking up to the hill on the gun emplacement, one will see the scenes of the Hoping Island, Badouzih, and Keeling Islet right in front of the hill. Walking straight ahead, you will see a complete gun emplacement for you to imagine all the wars occurred here.
