The ancient castle, covering an area of 8 hectares, is an impressive structure with high walls surrounding it. Inside these walls, stones are piled up to form the castle itself, which is concealed within layers of basalt rock. The walls are thick and strong, providing a formidable defense.
Beneath the castle, there is a tunnel shaped like the Chinese character ‘山’ (mountain), which is both wide and spacious, capable of accommodating 54 garrison troops. This tunnel is not only functional but also adds to the castle’s grandeur and spectacle.
At the front entrance of the Xitai ancient castle’s artillery fort, one can find double arches. Above the front door, a stone plaque inscribed with ‘Xiyu Xitai’ by Li Hongzhang is prominently displayed. Within the artillery fort, numerous vaults and tunnels extend in various directions, connecting the brick rooms on either side of the tunnel, which served as living quarters for officers and soldiers. These tunnels allowed for effective communication during battles.
Surrounded by cliffs on three sides, the artillery fort benefits from good ventilation and lighting. Standing on the arched corridor, one can still sense the heroic spirit and national pride that was once associated with guarding the land and repelling invaders. The castle stands as a historical witness to Penghu’s foreign relations.
Facing the entrance to Penghu’s inland sea and climbing the outer wall offers a breathtaking view of the ocean. The site has been recognized for its historical significance and is now listed as a first-class historical site. It is open to visitors all year round, with operating hours from 8:00 to 17:30.
