The first attraction when I reached Frankfurt was the Main Tower. It is owned by the heleda group. The observation platform is at 55th floor so it wasn’t pretty large like other top highest tower. It is wide open where you can get the fresh air and enjoy the refreshing breeze. The view was pretty where you can look around Frankfurt from the center of the city. There were nothing much you can do up there as there were no shops or cafe around. It was great to just hanging out and taking your time there.
