Augustine Castle is the main building in Augustine. It has the Dining Hall as well as all the staff offices and living quarters. Augustine Castle, like all the other buildings, is made of mud bricks and a grass roof and is reinforced with magic for stability.

Inside Aphra Castle are the classrooms for Wizarding Literature, History of Magic and Muggle Studies as well as the Library.

Inside Florian Castle are the classrooms for Charms, Defense Against the Dark Arts, Transfiguration and Ancient Runes as well as the Hospital Wing.

Inside Silvanus Castle are the classrooms for Care of Magical Creatures, Potions, Basic Healing, Arithmancy, Divination and Astronomy, which takes place in a small tower in the north-west side of Silvanus.

The dormitories are separated in six buildings scattered throughout the forest. Each building houses one year of students. Any student can go into the common area of any dormitory building, but they may only enter the actual dormitories of the year they are in.

Near Augustine Castle are extravagent gardens. It's a popular place for staff and students alike with many benches and beautiful plants and flowers. Sometimes the older Herbology students are charged with taking care of it.

There are six greenhouses - one for each year. They house many magical plants from docile to dangerous. Entrance into the greenhouses outside of class time is forbidden without permission of a professor.

Where there isn't beach, there is forest. Most of the island is covered in forest and while none of it is forbidden to enter, it can be quite dangerous in places that are far away from the paths that have been widely crafted between buildings.

There are many smaller clearings in the forest, but this main clearing is the largest of them all. It is a popular spot for students when not in class and also the location of the Flying lessons. Many are permitted to watch the Flying lessons for entertainment.

All around the edge of the island are beaches. They aren't extravagent or maintained for tourism, but they are still a popular spot for the students when the weather is permitting.
