The Augisteum played an important role in the life of major Roman cities. It was situated adjacent to the forum and was not so much a Temple, but rather more a college of priests, perhaps in practice more a club where the leading citizens could show their loyalty to Rome and to the Emperor.
It was situated in the basement of a new development where it had been been preserved in a somewhat gloomy cellar. It was a site for the enthusiast, but that means of course that it was a site for me, and possibly for you gentle reader. It was a temple for the worship of the Emperor Augustus – at least that was the story spun to the ignorant natives. Proper Romans knew of course that Augustus was a man not a god, but he was the person who had saved Rome from the chaos of the civil wars and had made it into the greatest nation on earth, so we are happy to go along with the idea, and to have at the centre of the town a shrine where we could celebrate his achievements and those of the great Roman Empire.
But it was more of a collegium than a Temple, with the central hall flanked by archive rooms and two large nymphaea or decorative fountains as well as a couple of shops unrelated to the Temple – but the Romans were always happy to mix up commercial and religion.
