A museum showing various historical treasures, most prominently a skeleton of a Dragon-type Pokémon (resembling Dragonite), is located in Nacrene City. Just to the left of the skeleton is an Armaldo Fossil. On the right side of the museum is an ancient tablet with an unknown script carved into it. Beneath this is a mask that was worn by ancient people at festivals, and three large bones that were once carried as weapons by a certain Pokémon (possibly Cubone or Marowak).
The Nacrene Gym is the official Gym of Nacrene City. It is based on Normal-type Pokémon. The Gym Leader is Lenora. The Nacrene City Gym is a Gym consisting of a library that require Trainers to find the right answers to opponents' questions through the readable books, before engaging them in battle. For defeating Lenora, Trainers receive the Basic Badge. The Gym can be found at the back of the Museum.
