Dewford Hall is located north of the Pokémon Center, and is the northernmost building in the town. A sign outside reads:
DEWFORD HALL "Everyone's information exchange!" Although it is a tiny island community, if someone says something "trendy" there, it quickly spreads throughout the rest of Hoenn.

This Gym is run by Brawly who will Battle any trainer how has won a Bagde from Roxanne and many citizens look up to Brawly and/or idolize him.
