Mount Olympus Academy is the school where very few mortals, immortal, goddessgirls and godboys attend school. It has subjects that all end with "ology", and Zeus is the Principal of the school. This school is very large, and appears to be a boarding school as well. Only Persephone does not reside there, because of her overprotective mother, Demeter's rules of being cautious.
The school is incredibly huge, and in the books, there is a large fountain on the school grounds. Lots of tall hedges surround the stairwell to the school, as the stairwell is high. There are pillars holding the front of the school around, and there is a door after the pillars stop. Through, the door, the classrooms and the lockers are there.
