the Temple of Antoninus and Faustina
The Temple of Antoninus and Faustina was built in 141 AD by Antonius Pius, to commemorate his wife, Faustina. She was an empress, who had died that year and officially canonized. Since 161 AD Antoninus himself was also honoured here.
The temple was changed into a church, which prevented later destruction. The facade was embellished with stairs and columns. The sculptured frieze extends from the front across the side walls of the church.
