Sōma Nakamura Castle

The Inner bailey (本 丸) of the castle was built on a hill that rises above the local plain between the Koizumi and Udagawa rivers. In the southwest corner of the Inner bailey was a three-story donjon (天 守, marked in red on the map), which was lost in 1670 by a lightning strike. It was never rebuilt. The inner bailey was surrounded by the Second Bailey (二 ノ 丸), which was divided into northern, eastern, southern and western sections, respectively. The Third Bailey formed a ring around the Second Bailey and was also divided into four sections. In the southeast was a separate area once containing the residence of the daimyō (marked "N" on the map), which is now occupied by the Nakamura Jinja, a Shinto shrine dedicated to the Sōma clan ancestors. This was protected by an outer enclosure (marked "E" on the map) called the Enzō-kuruwa (円 蔵 曲 輪).

The defences of the castle were the strongest to the north, where the moats could be cut to flood a large area, turning it into an impassable swamp. This was because the Sōma clan viewed the main threat to the castle as being from the Date clan to the north. However, Sōma Nakamura Castle never saw battle, and was surrendered to the forces of the Satchō Alliance during the Boshin War with no resistance.

After the Meiji Restoration, the new Meiji government ordered the destruction of all former feudal fortifications, and in compliance with this directive, all structures of Sōma Nakamura Castle were pulled down and demolished in 1871, leaving only the inner Ōte-ichimon main gate (marked "H" on the map). The site is now a public park, and nothing remains of the former castle aside from a monument and part of the moats to the north and east.
