The "Temple of Vesta" is a Roman temple in Tivoli, Italy, dating to the early 1st century BC. Its ruins sit on the acropolis of the city, overlooking the falls of the Aniene that are now included in the Villa Gregoriana.
It is not known for certain to whom the temple was dedicated, whether to Hercules, the protecting god of Tibur, or to Albunea, the Tiburtine Sibyl, or to Tiburnus, the eponymous hero of the city, or to Vesta herself, whose more familiar circular peripteral Temple of Vesta is to be seen in the Roman Forum. A rectangular temple stands nearby, equally difficult to attribute, often called the Temple of the Sibyl"1.
