The GERmanium Detector Array, GERDA, is designed to search for neutrinoless double beta (0νββ) 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 kg yr and a background level one order of magnitude lower than previous experiments. In this talk I will discuss the main physics results obtained from GERDA, focusing on the measurement of the half-life of neutrinoless double beta decay and on the future perspectives for the Phase II of the experiment.
