''Standing proudly among its brethren in the Roman Forum, the Tempio di Antonino e Faustina was originally erected in honour of the deceased wife of Emperor Antonius Pius, Faustina the Elder. 20 years after its inauguration, Antonius Pius also passed away and the temple was rededicated to both of them.''

In the 11th century, the Catholic Church decided to make use of the ruins and converted them into the church of San Lorenzo in Miranda, which you see now.
