Detail of the AstroTower in Astroland in Coney Island, June 2008

A Gyro Tower or Panoramic Tower is an evolution of the observation tower with a vertical moving platform. A Gyro Tower's observation deck is not simply raised to provide its passengers a spectacular view, it is also rotated around the supporting mast, either once in the raised position or while traveling up and down the center mast.

Gyro Towers are seldom part of funfairs but can be found more often in permanent amusement parks.
