The Temple of Hercules, formerly known as the Temple of Vesta, which stands in what was once the Forum Boarium (Cattle Market), dates back to the late 2nd century or early 1st century BCE.
It is uncertain to which deity the temple was dedicated, although Hercules, demi-god of victory and commercial activity, is a likely candidate.
Santa Maria del Sole
The temple owes its survival to the fact that at some point it was converted into a church. The date is unknown, but in 1132 it was called Santo Stefano alle Carrozze (St. Stephen 'at the carriages'). It was later renamed Santa Maria del Sole. The church was deconsecrated towards the end of the 19th century.
