when a long and narrow pond of 55m in length and 5m in width with a lot of bends and round stones embedded in the bottom was excavated at sakyo-sanjo-nibo-rokutsubo (the old address of the garden excavated in 1975 ), it drew attention that it was a garden that public kyokusui no en (the feast on a bent stream held in march 3 where attendants enjoyed composing poems while drinking ) were held . 1975（昭和50）年に発掘された平城京の左京三条二坊六坪からは、長さ55メートル、最大幅5メートルの、細長く屈曲し、底に玉石を敷きつめた池が発掘され、公的な曲水の宴が催された庭園として注目された。
