Immaculata is a High school located in Brockton Bay. It is first mentioned in Shell 4.7 as a Christian private school in the south end of the city. The school is located in one of the nicest parts of the city, south west of the 'Towers'. It is informally known as the "rich kids school".
It is one of, perhaps the only, school to have survived both Leviathan's attack and the Slaughterhouse Nine attack, as in Scarab 25.6 it is mentioned that a majority of students are wearing their uniform.
