生池城跡


戦国武将が日本の支配権を争っていた16世紀半ば、壱岐・五島を含む九州北西部を拠点に、武士であり、商人・海賊でもあった松浦党が活動していた。彼らは朝鮮半島との貿易や海賊行為、日本本土での商売を行い、大きな利益を得るとともに、ある程度の政治的な独立も果たした。


松浦党の有力者の一人は壱岐の源壱であり、島の中央部の丘陵に生池城を築いたとされる。この城は、最後の砦として設計されたもので、常時は人がいなかったと思われる。本丸は150×100メートルの平坦な土地で、三重の土塁と二重の空堀で守られていた。堀にかかる狭い土橋は計4か所あり、上から狙いやすい狭い場所に敵をおびき寄せるために、目立つように作られていた。


堀と土橋は現在もほぼ完全な形で残っており、丘の上では城壁の一部を見ることができる。城跡は近くの駐車場から徒歩で簡単にアクセスできる。

Site of Namaike Fort


In the tumultuous mid-sixteenth century, when rival warlords fought for control throughout Japan, a group of samurai merchants and pirates known as the Matsuura Band operated out of northwestern Kyushu, including the islands of Iki and Goto. They traded and raided along the Korean coast and did business in mainland Japan, accumulating considerable profits along with a measure of political independence.

One of the most influential Matsuura operatives was the Iki-based Minamoto no Ichi, who is thought to have built the hilltop Namaike Fort in the central part of the island. The stronghold was designed as a refuge of last resort, and was probably not manned at all times. Its main compound, a flattened 150-by-100-meter area, was protected by three layers of earthworks and a double dry moat. Access to the compound was via four narrow earthen bridges over the moat, one on each side, built in plain sight to draw enemies into a tight space where they would be easy to target from above.

The moat and earthen bridges remain almost entirely intact today; parts of the fort’s walls can also be made out around the top of the hill. The fort site is easily accessible on foot from a nearby parking lot.
