This monument represents the remains of Kirikida no Ido (Well of Kirikida).
It is said that Komachi first took a bath using water from this well when she was born.
This well was found at the mansion of Komachi’s father, Ono no Yoshizane. If you look at it from above, you can see that the natural stones are put together to form a pentagon. As this technique was not commonly used around this area at the time, but around Kyoto, it is important proof that it was made around the early Heian Era.
