The Cloudoseum is a stadium in the northwestern region of Cloudopolis where a variety of events can potentially take place, such as flight shows or theatrical productions. It is the largest area in the city in which is not directly connected to the main body of clouds.
Pegasi can reach the Cloudoseum via flight, while unicorns and earth ponies have to make use of a portal located southeast of the Cloudoseum. Entrances can be found on the west and south of the arena, with the south entrance being directly next to the portal. The Cloudoseum is at the second highest elevation within the city.
