岡崎公園グラウンドの南西、植え込みの中にあるレンガづくりの建造物。目立たない存在ですが、実は大正時代の博覧会遺跡で、大正天皇の即位式が京都で行われたのを記念して大正4（1915）年に開催された大典記念京都博覧会の電燈台座。『大典記念京都博覧会写真帖』にはこの台座が写った写真が掲載されています。

A Gatepost, Constructed for the Celebration of the Coronation and Corresponding Opening of the Kyoto Great Fair (a Corner Stone of Light)

In the southwestern part of Okazaki Park’s playground, a brick-built stone monument stands in a thick growth of trees. It might not draw much our attention, but this is the remains of an exhibition in Taisho era, which was held for congratulating an emperor on his coronation. This is for the corner stone of light used in the event which was held in 1915. In “Photo album of the exhibition for celebrating the coronation”, we can see a picture of this corner stone.
