Temple of Portunus

The Temple of Portunus is an ancient Roman temple in Rome, Italy. It was built beside the Forum Boarium, the Roman cattle market associated with Hercules, which was adjacent to Rome's oldest river port and the oldest stone bridge across the Tiber River, the Pons Aemilius. It was probably dedicated to the gateway god Portunus although the precise dedication remains unclear as there were several other temples in the area besides his. It was misidentified as the Temple of Fortuna Virilis from the Renaissance and remains better known by this name. The temple is one of the best preserved of all Roman temples.

It is dedicated to Portunus, the god of keys, doors and livestock, and so granaries, it is the main temple dedicated to the god in the city. During the Medieval period, the temple was converted to a Christian church dedicated to Santa Maria Egyziaca.
