Temple of Antoninus Pius and Faustina, adapted to the church known as San Lorenzo in Miranda

The Temple of Antoninus and Faustina is an ancient Roman temple in Rome, adapted to the church of San Lorenzo in Miranda. It stands in the Forum Romanum, on the Via Sacra, opposite the Regia.
The temple was begun in 141 AD by the Emperor Antoninus Pius and was initially dedicated to his deceased and deified wife, Faustina the Elder. When Antoninus Pius was deified after his death in 161 AD, the temple was re-dedicated jointly to Antoninus and Faustina at the instigation of his successor, Marcus Aurelius.
The building stands on a high platform of large peperino blocks. The later of two dedicatory inscriptions says, "Divo Antonino et Divae Faustinae Ex S.C." meaning, “To the divine Antoninus and to the divine Faustina by decree of the Senate.”
The ten monolithic Corinthian columns of its pronaos are 17 metres tall. The rich bas-reliefs of the frieze under the cornice, of garlanded griffons and candelabri, were often copied from the sixteenth through the nineteenth centuries.
The temple was converted to a Roman Catholic church, known as San Lorenzo in Miranda, perhaps as early as the seventh century, but it is only attested from the eleventh century Mirabilia Urbis Romae. "Miranda" may derive from the name of a benefactress. It was then thought that this was where St Lawrence had been sentenced to death.
