This sanctuary, together with the other temples for the imperial cult, such as the Temple of the Genius Augusti (below) and the Portico of Concordia Augusta, was built in an area formerly taken up by shops. The large building, completely open on the Forum, was fitted with a central altar, where sacrifices could be offered for the emperor as well as for citizens of Lari. There are two large exedras on the two sides of the central apse and several niches intended to house the statues of the imperial family. Only a few fragments of the rich marble covering are preserved, which was destroyed shortly after the eruption 79 AD.

The Sanctuary was built prior to the earthquake of 62 AD but after the rule of Augustus (first decades of the 1st century AD).

Date of excavation: 1817.
