Abstract: Neutrino physics represents today a hot topic in elementary particle physics, due to the observations of flavour oscillations both in the atmospheric and in the solar sector. This proves the existence of finite neutrino masses. In order to fix their absolute values, sensitive experiments on Neutrinoless Double Beta Decay (a rare nuclear process) must be carried on. The experiment here described, named Cryogenics Underground Observatory for Rare Events (CUORE), can extend the neutrino mass sensitivity down to 30 meV. CUORE will consist of a large, closely packed, high-granularity array of 1000 tellurite (TeO2) low-temperature calorimeters, operated at 10 mK and with a total mass of 800 kg. The final structure of the detector and the preliminary tests are presented and discussed.
