The stadium is an oval-shaped, open building that features a stand with three floors and several screens for the festival.
The arena of the stadium itself consists of a circular space with a flat square of concrete in the center, surrounded by grass. It also has many gates that lead in and out of the field.
During the fighting tournament, a concrete platform is built by Cementoss in the middle of the field, with torches located in each of the platform's corners and a concrete throne from where Cementoss observes the fights during the festival.
The stadium also features a branch nurse's office, as well as waiting rooms for the participants.
