The Curia Calabra was a religious station or templum used for the ritual observation of the new moon in ancient Rome. Although its exact location is unclear, it was most likely a roofless enclosure in front of an augural hut (auguraculum), on the southwest flank of the Area Capitolina, the precinct of Temple of Capitoline Jupiter. Servius identifies the Curia Calabra with a Casa Romuli ("Hut of Romulus") on the Capitoline, but Macrobius implies that it was adjacent to the Casa.
