Castelia City Pokémon Gym Leader: Burgh "Premier Insect Artist"
In Black and White the Castelia Gym is designed like a huge beehive. It contains many small hexagonal rooms, several which are cut off by walls of honey which are at first barricaded by gates. There are buttons which are placed in the center of most of the rooms, and if certain buttons are stepped on, they trigger the gates to descend. However, a few buttons make Trainers appear and battle the player instead. The player is able to walk through the walls of honey once these gates have gone, giving them the availability to venture through the Gym and battle Burgh. The Gym is also decorated with pictures painted by Burgh himself. The room in which Burgh stands is a little different to the previous rooms. The hexagonal room leads to a set of stairs, which leads up to a platform on which Burgh stands.
In Black 2 and White 2 the Gym has been redesigned. The Gym is now made up of multiple levels of silk and the player must use silk cocoons to go between the different levels, eventually making their way to the top floor where Burgh is.
It is a lilac building with huge glass windows on the walls and roof and a plant pattern above the front door. It is surrounded by skyscapers and trees on a street called Gym street. Leading to the front door are camo tiles. Inside it is a botanical garden with a path for Trainers to walk on. Bug Pokémon such as Sewaddle also reside here. Some of the trees are from Pinwheel Forest. The battlefield rises through the floor, it is a sandy terrain. Around the battlefield is more foliage with two huge propagators either side of it.
