One of many yakata of the Nishina in Ōmachi, the site was converted into a temple by Oda Nobunaga in 1582 after the Nishina's defeat at Takatohjō. The temple was then largely destroyed during the anti-Buddhist purges of the Meiji Revolution. A modern main hall, some temple walls, gates and halls can be found, but any fortification remains are hard to identify.
I visited the temple and found some suggestive shapes in the earth around its necropolis, but little that I could positively point to. I thought I found a karabori (dry moat) segment but could not be sure. Edo Period maps depict the temple of Seiryūji surrounded by a square karabori, the chief evidence of the former yakata (fortified manor house) used by the Nishina, one of several in town.
