This stone wall was discovered by an excavation in 2014.

In the next year, parts of the stone wall were gradually revealed.

The stone wall was built using “Nozurazumi - the use of natural stone”, identical to the ones used in castle, piling them on top of each other.

Stones are placed side by side and arranged so that the sides of rocks are perfectly aligned in a straight line using a technique called “Nunozumi”.

Judging from the condition of the stone walls, it is estimated to have be constructed during the reign of Yoshiharu Horio (1590s).

Maintenance was conducted in 2018 while planning for the preservation of the remains.

The main methods used in the maintenance of the remains are as follows:

・Make a fill in the bottom layer of the stone wall, containing the degradation of its foundations.

・Paste the same material on the upper layer of the stone wall, applying texture.
