The distinctive triangle-shaped fort is a landmark in Kinmen. The moat-like trench surrounding it was a defense measure against invaders. The minefield encircled by barbed wires on the beach, as well as the soldiers stationed here, are long gone. But you can still see tanks……and perhaps, butterflies and birds. In the late spring and early summer, the yellow beach primrose flowers attract butterflies and migratory blue-tailed bee-eaters.Starting in November, in the winter, come at dusk to see flocks of migratory cormorants flying in from the sea. They're headed for trees on the shores of nearby Lake Ci to roost for the night.Throughout the year at low tide, you should be able to watch shorebirds along the coastline here.
