Key information:

The temple was dedicated to Portunus, god of Rome’s Tiber River harbor, on this location as early as the 4/3C BC, eventually related to nearby Pons Aemilus (2C BC).   What is standing today, of tuff and travertine construction, is a 1C BC construction, but the stucco decoration on the frieze level is imperial (1C AD).  The structure survives because it was converted into a church in 872. The Fascist- era construction of the modern road destroyed the medieval neighborhood that had developed and removed the church accouterments of the temple as church. What remains from the church phase of the structure are a few 9C frescoes preserved inside.  

It was recently restored by World Monuments Fund; the roof is new, the stone has been cleaned, and the remains of stucco plaster are cleaned and legible on the south side.
