Sierraville Gym

Sierraville Gym is located in the centre of a huge stone fortress carved into the very cliff face of Mt. Marsmonte. The expansive gym is by far the largest in Solastella and it is filled with every luxury available - the battles here take place in the deepest room of the building, simultaneously ancient and high-tech, where Solastella’s brightest brains come to conduct non-Pokémon related research.
