The GERmanium Detector Array, GERDA, is designed to search for neutrinoless double beta decay of ⁷⁶Ge. The new shielding concept of GERDA is implemented by operating bare Ge (enriched in ⁷⁶Ge) detectors in cryogenic liquid argon, surrounded by an additional shield of ultra-pure water. At present, GERDA has completed the phase I with an achieved exposure of about 20 kgxyr and a background level one order of magnitude lower than previous experiments. In this talk I will discuss the main physics results obtained by GERDA Phase I and on the future perspectives for the Phase II of the experiment, focusing on the measurement of the half-life of neutrinoless double beta decay.
