Temple of Jupiter

The Temple of Jupiter, Capitolium, or Temple of the Capitoline Triad, was a temple in Roman Pompeii, at the north end of its forum. Initially dedicated to Jupiter alone, it was built in the mid-2nd century BC at the same time as the Temple of Apollo was being renovated – this was the area at which Roman influence over Pompeii increased. So Roman Jupiter superseded the Greek Apollo as the town's leading divinity. Jupiter was the ruler of the gods and the protector of Rome, where his temple was the center of Roman religion and of the cult of state.
