Stone Quarries for Edo Castle

The Stone Quarries for Edo Castle (Edojō Ishigaki ishichōba ato) are the remnants of stone quarries used to provide the massive amount of stone necessary to construct the extensive moats and defensive fortifications of Edo Castle under the Tokugawa shogunate in 17th century Japan. These sites are located in what are now the cities of Odawara, Kanagawa in Kanagawa Prefecture, and Atami and Itō, Shizuoka Prefecture. These 170 sites were collectively designated a National Historic Site of Japan in 2016.
