Dragonspiral Tower (Japanese: リュウラセンの塔 Dragonspiral Tower) is an old tower where Zekrom and Reshiram were sealed in the Dark Stone and Light Stone after the war thousands of years ago. It is located in the western part of Unova, just above Icirrus City. Though it is not known who built it or when it was built, it is the oldest structure in Unova. It is said this is where legendary Pokémon are created and slumber.
