A large palace for Princess Ruth Keʻelikōlani, known as Keoua Hale was built on this site in 1878. After she died in 1883, her estate passed to her first cousin,
Bernice Pauahi Bishop, who died in 1884. Later, the palace was sold to the government to be used for educational purposes. In 1895, Honolulu High School (formerly Fort Street English Day School) classes were held there until 1907, when the school was renamed
McKinley High School and relocated to a new building facing
Thomas Square. (That building later housed the
Linekona School and is now the Honolulu Museum of Art School). Central Grammar School then took McKinley's old place in Keʻelikōlani's former palace. In 1920, Central Grammar School was designated a forerunner of what would become the "English Standard" type of public school. Soon thereafter, English-language exams were required for entrance. Plans for a new building were commissioned to accommodate the rapid growth of students going on to secondary schools during the booming 1920s. The palace was demolished, and the makai wing of the new building opened in 1925. The school was originally named Keʻelikōlani School, but was renamed Central Grammar School in 1927 after it became too difficult for others to pronounce (One can still see the name "Keelikolani School" engraved over the first-story windows on that side.) After the other two wings were completed in 1927, Central Grammar School became Central Junior High School, one of only six public secondary schools in Honolulu at the time. In 1932, all junior high schools were renamed intermediate schools. The effort to change the name began in 2019, and the change was approved by the Board of Education in September 2021. The renaming celebration took place on February 9, 2022. == Academics ==
