The GERDA experiment searched for neutrinoless double-beta (0νββ) decay of ⁷⁶Ge by operating Ge detectors made from ⁷⁶Ge enriched material in a 64 m³ liquid argon cryostat located in Hall A of LNGS. Data taking stopped in Febr 2020. The final result of the 0νββ decay search is a limit of 1.8x10²⁶ yr (90 % C.L.) published in PRL. The LEGEND collaboration took over the setup with the goal to increase the amount of enriched Ge detectors to about 200 kg in the same cryostat.
