The construction of Roman temple in Córdoba began during the reign of Emperor Claudius (41-54 AD) and ended some forty years later, during the reign of Emperor Domitian (81-96 CE). Presumably it was dedicated to the imperial cult. The temple underwent some changes in the 2nd century, reforms that coincide with the relocation of the colonial forum.
In the area had already been found architectural elements, such as drums of columns, capitals, etc. all in marble, so the area was known as los marmolejos. This area of Córdoba could become between the 1st century and the 2nd century, as the provincial forum of the Colonia Patricia, title that received the city during the Roman rule.
The building was situated on a podium and consisted of six columns on its front facade and ten columns on each side. Currently, the only remains left of the building are its foundation, the stairs, the altar and some shafts of columns and capitals.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
