Paichai Hakdang School, a predecessor of Paichai High School, was a modern private school founded by the American missionary Henry G. Appenzeller in 1885. King Gojong presented the school with a hanging board bearing the school’s name, Paichai, meaning a “house for training useful talented people.”
The school helped students from poor households earn tuition fees through jobs created within the school. Meanwhile, Sammun Publishing, operated by Paichai students, strived to enlighten the public by publishing the Dongnip Shinmun (by Seo Jae-pil) and the news bulletin of the Hyeopseonghoe (enlightment movement association).
With the relocation of Paichai High School elsewhere, only the East Wing remains of the original structure built in 1916, which is now used as a history museum.
