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 destroyed during the anti-Buddhist purges of the Meiji Revolution.
I cannot be sure of the extent of Dainenji-yakata and due to its proximity to Seiryūji-yakata. I'm not sure which, if either, was the bigger site. It seems that Seiryūji-yakata retained its karabori as part of the temple Seiryūji, but little remains there today. However, what is probably a segment of dorui (earthen embankment) attests to the ruins of Dainenji-yakata. The temple Dainenji no longer exists. Edo Period maps indicate a temple with karabori (dry moats) surrounding it, which I gather is Seiryūji, but no such moat for Dainenji, so perhaps the karabori there was filled in even in the Edo Period, or they only ever constructed dorui there in the first place, although usually piling up dorui also creates a hori.
