The main symbol of Dongjak District is the Snowy Heron. A cartoon character named Roya, a baby snowy-heron, can be seen on signs, banners, and even light poles throughout the gu. According to the offical website, use of the snowy heron is meant to symbolize the "clean, beautiful, and noble spirit" of Dongjak's people. The emblem, found at most offical buildings, depicts the snowy heron soring into the sky.
