The Temple of Portunus beside the Tiber in Rome, remarkably well preserved because it was converted into a Christian church in the medieval period, remains one of the clearest surviving examples of the developed podium temple form, its Ionic columns engaged along three sides and freestanding only across the front porch. Larger and more famous examples, including the Capitoline Temple of Jupiter Optimus Maximus, Rome's principal state temple, followed the same essential logic at far greater scale, with the Capitoline temple additionally departing from Greek precedent in housing not one but three cult statues side by side, for Jupiter, Juno and Minerva, the Capitoline Triad.
Because Roman architects and engineers spread this podium form across the empire alongside Roman civic and military presence, provincial temples from Gaul to North Africa to the eastern Mediterranean adopted the same frontal, elevated arrangement for centuries, and the type's influence did not end with Roman religion itself. Renaissance and later Western architects, working from surviving Roman buildings and from Vitruvius' text, revived the podium temple's proportions and frontal emphasis for churches, government buildings and monuments long after the gods it had originally housed went unworshipped, so that the shape built for Jupiter and Juno became, centuries later, a template used to build monumental architecture for entirely different purposes.
