What Roman temple in Vienne, France, is dedicated to Augustus and his wife Livia?

The Roman temple in Vienne, France, dedicated to Augustus and Livia is the Temple of Augustus and Livia.

The building was erected in the late 1st century BC or early 1st century AD at the centre of ancient Vienna, in what was likely the city's forum. It served the imperial cult, linking religious devotion with loyalty to Augustus and his ruling household. Livia was added to the dedication after her deification in AD 42.

Architecturally, it is a Corinthian temple of the pseudo-peripteral, sine postico type: columns surround three sides, while the rear is closed by a wall. Its six-column façade and elevated podium give it the imposing appearance associated with Roman state architecture.

The monument survived partly because it was reused as a Christian church, later becoming a Temple of Reason, a commercial court, a museum and a library. It was listed as a French historical monument in 1840. It is often compared with the Maison Carrée at Nîmes, but that is a separate Roman temple.
