The capitol is a temple from the 2nd century CE, principally dedicated to Rome’s protective triad: Jupiter Optimus Maximus, Juno Regina et Minerva Augusta. It has a secondary dedication to the wellbeing of the emperors Lucius Verus and Marcus Aurelius; judging by this reference, the capitol must have been completed in 166-167 CE.
The capitol is exceptionally well preserved, which is a consequence of its inclusion in the Byzantine fortification. A series of eleven stairs lead up to the front portico. The temple front’s Corinthian columns are eight metres tall, on top of which is the perfectly preserved pediment. The pediment bears a depiction of emperor Antoninus Pius’s elevation to godhood. The emperor is being carried by an eagle. The base of the cella still features alcoves for three statues. The middle alcove houses a colossal statue of Jupiter.1
