CUORE (Cryogenic Underground Observatory for Rare Events) is a ton-scale experiment for the search of neutrinoless double beta decay in 130Te with tellurium oxide bolometers, with a projected sensitivity close to the inverted mass hierarchy region. The CUORE detector design and background budget has been validated by CUORE- 0: an array of 52 TeO2 bolometers built using the same protocols developed for CUORE and running at the Gran Sasso Laboratories for two years, up to spring 2015. Final result on neutrinoless and two neutrino double beta decay from CUORE-0 are presented. CUORE-0 performance in terms of background and energy resolution fully supports the expectations for the CUORE sensitivity. The status of CUORE, that is now in its final construction stage, is reported: all towers have been assembled and installed inside the cryostat, which is being prepared for the cool-down. Data operations are foreseen to begin within this year.
