Does lighthouse point have a lighthouse?
Good question! Lighthouse Point Certainly contains a round tower, but is it really a lighthouse?
The definition of a lighthouse is “is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses, and to serve as a navigational aid for maritime pilots at sea or on inland waterways.”
The round structure at Lighthouse Point is certainly geographically positioned near the sea, which would suggest that it is indeed a lighthouse. However, since the player cannot enter the structure, and no point in Konikoni City gives a perspective to see the top of the structure, we cannot confirm that the tower is outfitted with an light-emitting system and therefore the question remains uncertain.
The Olivine Lighthouse in Johto is operated by an electric-type pokémon Ampharos. At Lighthouse Point in Alola, the player encounters a woman training several Pikachu, perhaps preparing them to operate the supposed lighthouse.
Thanks for your question!
