The games' Paldea region is inspired by the real-life Iberian Peninsula in Europe where countries like Spain and Portugal are. In a lot of areas of Paldea, this can be seen:
•The Glaseado Mountains are based on the Pyrenees Mountains that separate Spain and France
•The large amount of caves in the region are possibly based on Spain's own large amount of caves, such as the Malaga Province's Caves of Nerja
•The real life Andalusia Region, known for its olive fields and sunflowers, is the inspiration for the Paldean cities of Cortondo and its similar olive fields, and Artazon and its sunflora connection
•Naranja/Uva Academy is architecturally based on La Sagrada Familia (The Holy Family) in Barcelona, an old landmark church that is still in an unfinished state to this day, among other inspirations.
•The regional variants on old Pokémon also reflect this; for instance, Paldea's black-furred Fighting-type variant of Taurus represents a Spanish Fighting Bull.
