Two important Roman monuments still stand at Vienne. One is the Early Imperial Temple of Augustus and Livia, a rectangular peripteral building of the Corinthian order, erected by the emperor Claudius, which owes its survival, like the Maison Carrée at Nîmes, to being converted to a church soon after the Theodosian decrees and later rededicated as "Notre Dame de Vie." (During the Revolutionary Reign of Terror it was used for the local Festival of Reason.) The other is the "Plan de l'Aiguille", a truncated pyramid resting on a portico with four arches, from the Roman circus. Legends from the 13th century mention Pontius Pilate's death in Vienne. Later legends held that the pyramid was either the tomb of Herod Archelaus or of Pontius Pilate.
