Location from pokemon-kalos by
Lumiose City's glass-and-steel spire — the Lumiose Gym at night, an observation tower by day, and Clemont's home.
Prism Tower is the symbol Ash sees first when he arrives in Kalos — the beacon that pulls him toward Clemont. Inside it is Gym, home, and laboratory stacked vertically. Clemont's inventions detonate in the basement workshop with some regularity. Clembot runs the first-floor reception. The top-floor arena is where Ash earns the Voltage Badge after a three-stage elevator challenge.
Fifty-story open lattice of steel and blue glass, needle-shaped at the top, dome-shaped at the base. By night the lattice lights up in cycling patterns of yellow and blue. At the summit: a Gym battlefield ringed by floor-to-ceiling windows. An elevator that malfunctions in character-revealing ways.
Also known as: Prism Tower, Miare Tower
