史跡東京湾要塞　千代ヶ崎砲台跡

千代ヶ崎砲台とは

千代ヶ崎砲台は神奈川県横須賀市浦賀にある東京湾要塞を構成する明治時代に建造された砲台の一つです。千代ケ崎砲台は江戸時代の文化8（1811）年、江戸幕府の命令で海防の為に会津藩が作った台場・平根山に、明治25年（1892年）から明治28年（1895年）にかけて陸軍によって建設されました。明治時代につくられた東京湾要塞の中での千代ケ崎砲台の任務は観音崎の砲台群の側防（そくぼう）と浦賀湾全面海域の防禦です。対岸の富津元洲砲台とともに、援助砲台に位置づけられていました。

築城当初の姿を良好に残し、近代日本の軍事および築城技術の様相を具体的に理解することができるため、猿島砲台跡と合わせて、近代の軍事施設に関する遺跡としては日本で初めての国史跡の指定を受けました。

Introduction of Chiyogasaki Battery Site

The Chiyogasaki Battery Site is one of the modern fortified batteries built in the 19th century that make up the Tokyo Bay Fortress, located in Uraga, Yokosuka City, Kanagawa Prefecture. The Chiyogasaki Battery was originally built in 1811 by the Aizu Clan from Fukushima for sea defense by order of the Edo Shogunate, and was later constructed between 1892 and 1895 by the Japanese Army in the 19th century. The role of the Chiyogasaki Battery was to defend the batteries scattered around the Kannonzaki Fortress and to defend the entire sea area of Uraga Bay. Together with the Futtsu Motosu Battery on the opposite shore, it was positioned as a battery to support the fortress.

The Chiyogasaki Battery Site, together with the Sarushima Battery Site, was designated as Japan's first national historic site (Japanese Heritage) as a site related to modern military facilities, because it retains the original appearance of the fortress and provides a concrete understanding of the aspects of Japanese military and fortification construction techniques in the 19th century.
