A temple ("aedes") of Juno Lucina was built in 375 BC in the grove sacred to the goddess from early times. It stood precisely on the Cispius near the sixth shrine of the Argei. probably not far west of the church of S. Prassede, where inscriptions relating to her cult have been found. The grove should have extended down the slope south of the temple. As Servius Tullius ordered the gifts for the newborn to be placed in the treasury of the temple though it looks that another shrine stood there before 375 BC. In 190 BC the temple was struck by lightning, its gable and doors injured. The annual festival of the Matronalia was celebrated here on March 1, day of the dedication of the temple.
