The Roman Forum and the Palatine Hill, Rome.

Top left: “The Temple of Venus and Roma (Latin: Templum Veneris et Romae) is thought to have been the largest temple in Ancient Rome. Located on the Velian Hill, between the eastern edge of the Forum Romanum and the Colosseum, it was dedicated to the goddesses Venus Felix (‘Venus the Bringer of Good Fortune’) and Roma Aeterna (‘Eternal Rome’). The architect was the emperor Hadrian and construction began in 121. It was officially inaugurated by Hadrian in 135, and finished in 141 under Antoninus Pius. Damaged by fire in 307, it was restored with alterations by the emperor Maxentius.”

Top right: “The Arch of Septimius Severus (Italian: Arco di Settimio Severo) at the northwest end of the Roman Forum is a white marble triumphal arch dedicated in AD 203 to commemorate the Parthian victories of Emperor Septimius Severus and his two sons, Caracalla and Geta, in the two campaigns against the Parthians of 194/195 and 197–199. After the death of Septimius Severus, his sons Caracalla and Geta were initially joint emperors. Caracalla had Geta assassinated in 212; Geta’s memorials were destroyed and all images or mentions of him were removed from public buildings and monuments. Accordingly, Geta’s image and inscriptions referring to him were removed from the arch.”
