Unova's enormous metropolis — a New-York-modeled skyscraper jungle, home to Burgh's Gym, Team Rocket's Unova field office, and the region's media hubs.
Castelia is Unova's beating heart. Commuters stream. Street musicians hold corners. The Gym, run by Burgh, is tucked into an arts loft above a gallery. Dr. Zager's Unova operations office is in an anonymous high-rise near the harbor. It's the city where the Meloetta arc effectively begins — where Meloetta first meets Ash on a rooftop and sings with Pikachu at sunset.
A dense grid of gleaming skyscrapers, yellow taxis, elevated subways, a central harbor dotted with freighters. Prism Tower's sibling — the Castelia Tower — dominates the skyline. Streets smell of hot pretzels, exhaust, ocean, and Casteliacones (the city's signature ice cream).
