Located at the northernmost tip of Fengguai Peninsula, the Dutch established the first Western-style fortress in Taiwan in 1622 due to trade needs. Subsequent eras saw the construction of numerous gunpowder batteries and military fortifications, leaving behind historical remnants such as the French Military Memorial and other military relics. Xie Toutu Mountain, resembling a coiled serpent's head and situated on a small protruding peninsula at the northern edge of Fengguai Village, offers a view of Magong City and Magong Inner Harbor. Opposite the mountain lies a peninsula shaped like a turtle's head, aptly named "Jinguatu (Golden Turtle Head)." All vessels entering Magong Harbor must pass through this strategic location; the natural formations of "the Sacred Turtle floating northward and the Golden Snake coiling southward" seem to guard the harbor together. This geographic significance has made the site a repository of historical artifacts. Notably, during the Sino-French War, the French occupation of Penghu led to the deaths of hundreds of soldiers due to disease, prompting the establishment of the French Military Monument. Another significant remnant is the Japanese Matsushima Monument on Xie Toutu Mountain, commemorating the 1895 incident where the Japanese Matsushima warship sank after an ammunition explosion in Magong Harbor. Northeast winds carried over 200 victims ashore along the northern coast, leading to the placement of this memorial.
