沼田小早川氏の一族の多くは、活路を海へ求めました。その一つ、浦氏の城です。交通上の要地にある海上につき出した、標高25mの小丘の上にあります。城の北方にある勝運寺には、浦宗勝の画像や墓など、城主であった浦氏ゆかりの物が蔵されています。城跡の西は深い湾となっており、かつて船溜だったと言われています。
Many members of the Numata Kobayakawa clan sought their way to the sea. This is the castle of the Ura clan. The castle is located on a 25-meter-high hill that juts out into the sea at a strategic point for transportation. The Shounji Temple, located to the north of the castle, houses the image and tomb of Muneyoshi Ura, as well as other items related to the Ura family, who were the owners of the castle. To the west of the castle ruins is a deep bay, which is said to have once been a boatyard.
