When steam heaters were introduced during Taisho period these fireplaces were abolished and the chimney pipes were removed, but the mantelpieces furnished in each place such as in the lobby and so on still exist up until the present.
大正時代にスチームヒーターを導入した際にこれらの暖炉は廃止され、煙突は撤去されたものの、ロビーをはじめ各所に設けられていたマントルピースは現在に至るまで存続している。
