The Capitol is a Roman temple from the 2nd century, principally dedicated to Rome’s protective triad: Jupiter Best and Greatest (Jupiter Optimus Maximus), Juno the Queen (Juno Regina), and Minerva the August (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 AD 166-167.

Thomas d’Arcos identified the Capitol as a temple of Jupiter in the 17th century.
It was the object of further research at the end of the 19th century, led in particular by the doctor Louis Carton in 1893.
The walls, executed in opus africanum style, and the entablature of the portico were restored between 1903 and 1910.
Claude Poinssot discovered a crypt beneath the cella in 1955.
The most recent works were carried out by the Tunisian Institut national du patrimoine between 1994 and 1996.

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 8 m (26 ft) 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.

The discovery of the head of a statue of Jupiter has led Poinssot to suggest that the crypt dates from the period of Christianity’s triumph over the old religions.
St-Amans does not exclude the possibility that the crypt was built at the same time as the Byzantine citadel, of which the forum and capitol formed the nerve center.

The construction of the Capitol at Dougga occurred at the same time as the construction of other monuments of the same type elsewhere in North Africa, which Gros explains as a consequence of the greater proximity of the imperial cult and the cult of Jupiter.

Near the Capitol are the "square of the Rose of the Winds"—which is named after a compass rose that is engraved on the floor—and the remains of the Byzantine citadel, which reused a section of the ruins after the city's decline.
