  The Cryogenic Underground Observatory for Rare Events (CUORE) is a bolometric
experiment for neutrinoless double-beta decay in $^{130}$Te search, currently
taking data at the underground facility of Laboratori Nazionali del Gran Sasso
(LNGS). The CUORE cryostat successfully cooled down a mass of about 1 ton at
$\sim$7\,mK, delivering an uniform and constant base temperature. This result
marks a fundamental milestone in low temperature detectors techniques, opening
the path for future ton-scale bolometric experiments searching for rare events.
In this paper we present the CUORE cryogenic infrastructure, briefly describing
its critical subsystems.
