The temple—as indicated by the inscription—was dedicated by the Senate to Faustina in AD 141 and, when he died, to her husband the emperor Antoninus Pius (138-161 AD). The long walls of the cella, in square peperino blocks, were originally covered in marble. At the centre of the staircase, added later, are the remains of an altar. The statue visible behind the six columns of the façade probably belonged to the temple, which in the Middle Ages was turned into the church of San Lorenzo in Miranda. Later pope Urban V reused construction materials from inside the church to restore the Lateran Palace.
