Rome

Ancient Roman temples are among the most visible archaeological remains of Roman culture, and are a significant source for Roman architecture. Their construction and maintenance was a major part of ancient Roman religion. The main room (cella) housed the cult image of the deity to whom the temple was dedicated, and often a small altar for incense or libations. Behind the cella was a room or rooms used by temple attendants for storage of equipment and offerings.Public religious ceremonies took place outdoors, and not within the temple building. Some ceremonies were processions that started at, visited, or ended with a temple or shrine, where a ritual object might be stored and brought out for use, or where an offering would be deposited. Sacrifices, chiefly of animals, would take place at an open-air altar within the templum.

The Temple of Antoninus and Faustina is an ancient Roman temple in Rome. 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 temple was later converted to a Roman Catholic church.
