Forum Romanum. western part, south-eastern view from the Capitoline Hill to the Palatine Hill.

Western part of the Forum Romanum, with the Arch of Septimius Severus left, the Column of Phocas at center and the Temple of Saturn at the foot of the Capitoline Hill right, the Temple of Vesta and the Palatine Hill distant in background.

The Capitoline Hill (Latin: Collis Capitōlīnus; Italian: Campidoglio), between the Forum and the Campus Martius, is one of the seven hills of Rome. It was the citadel (equivalent of the ancient Greek acropolis) of the earliest Romans. The name capitol seems to have meant "dominant height".

The white marble Arch of Septimius Severus (Italian: Arco di Settimio Severo) at the northwest end of the Roman Forum is a 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. It´s close to the foot of the Capitoline Hill.

The Column of Phocas (Italian: Colonna di Foca) is a Roman monumental column in the Roman Forum of Rome, Italy. Erected before the Rostra and dedicated or rededicated in honour of the Eastern Roman Emperor Phocas on August 1, 608, it was the last addition made to the Forum Romanum. The fluted Corinthian column stands 13.6 m (44 ft) tall on its cubical white marble socle. On stylistic grounds, the column seems to have been made in the 2nd century for an unknown structure, and then recycled for the present monument.

The Temple of Saturn was completely reconstructed by Munatius Plancus in 42 BC. The present ruins represent the third incarnation of the Temple of Saturn, replacing a second incarnation that had been destroyed by the fire of Carinus in AD 283. Gradual collapse has left nothing but the remains of the front portico standing.

The Palatine Hill (Latin: Collis Palatium or Mons Palatinus; Italian: Palatino) is the centermost of the Seven Hills of Rome and is one of the most ancient parts of the city. It stands 40 metres above the Forum Romanum.
