Excavations in the historic core of Saguntum have revealed the remarkably well-preserved foundations of a 1st-century CE Roman temple dedicated to Janus, the god of beginnings and transitions. The find is extraordinary due to the discovery of twelve ceremonial bronze keys deposited in a ritual pit near the threshold, a rare archaeological confirmation of Janus-related liturgical practices.
The temple features a classic podium-style architecture with a deep pronaos and a single cella. Fragments of a marble statue showing the characteristic two-faced deity were also recovered, along with inscriptions honoring a local magistrate who funded the temple's construction during the reign of Vespasian.
