Dragonspiral Tower

22 Pokémon can be caught at Dragonspiral Tower in Unova — highlighted on the map below.

Reputed to be Unova's oldest structure, Dragonspiral Tower stands just north of Icirrus City in the region's west, its builders and age unknown. Legend holds that Legendary Pokémon are born and sleep there, and it is where Zekrom or Reshiram lay sealed within the Dark Stone or Light Stone after an ancient war, until N awakens the dragon. A moat impassable even with Surf isolates the tower, so only its entrance is reachable at first in Black and White; Team Plasma forces the way open after the player earns the Freeze Badge.
