Castelia City is a city in Pokémon Black and White. It is enormous with many areas including the Castelia Harbor, Market, and the Sky Arrow Bridge. It is also the largest Pokemon city ever, (kicking Saffron City and Goldenrod City out.) and it is also most likely three times the size of Goldenrod and Saffron combined. When you travel through Castelia City, the camera will zoom in and out, and when you leave, the camera will show you Castelia City from a distance. It looks like it could be the area where you can travel to other regions, but you can't though (you can only travel through the Unova/Isshu region). It is based on Manhattan.The Poke Center is west of Castelia Street close to Royal Unova's pier:Cruise Dock.It has the Battle Company,Passerby Analytics HQ,Studio Castelia,Casteliacone,Cafe Sonata,GAME FREAK building,and the Pokemon massager.
