Tempio di Vesta (Temple of Vesta)

The Tempio di Vesta, a prominent example of ancient architecture, was once the central sanctuary of Rome in the Roman Forum. It was distinguished by its circular design and housed the Sacred Fire of Vesta, guarded by the Vestal Virgins.
History+
According to tradition, the temple dates back to Rome's second king, Numa Pompilius, and was originally conceived as a round hut, reminiscent of early Roman dwellings. Inside, the Penates of the state were kept, including the Palladium, a statue of Pallas Athena, which Aeneas is said to have saved from Troy. The sacred interior was accessible only to a select few, while the temple was otherwise open to the public. The Sacred Fire was rekindled annually on March 1st; its extinguishing was considered a great misfortune.
