We propagate an atomic wavepacket in a gravitational cavity which is modulated by means of an external periodic driving force. We show that in classical evolution it displays classical chaos, whereas in the quantum domain the wavepacket exhibits dynamical localization. Moreover, we also find dynamical revivals in the quantum evolution and prove that this is a generic characteristics of all driven systems.
