The larger Sannomaru enceinte used to be buffered by two moats and encircled the inner castle enceintes from the east and the south. Various temples and villas, as well as administrative buildings, were located on its grounds. On the eastern side, the large stone foundations of the Sannomaru East Gate are still visible. Located in the Sannomaru enceinte were the Tōshō-gū shrine and the Tennosha shrine, which housed the guardian deity of the castle. Both shrines played an important role in the religious life of the castle, and rituals and festivals were held in honour of the spirits enshrined. Both shrines were moved in the late 19th century during the Meiji era. None of the other original wooden structures of the Sannomaru have survived, but the area is still the administrative center of the city of Nagoya and the surrounding Aichi Prefecture, with Nagoya City Hall, the Aichi Prefectural Government Office, and other administrative buildings and offices being located there. Roads and areas such as Sotobori-dori (Outer Moat Road) and Marunouchi begin at the castle.
