NOTES: The Temple of Vesta, which had been rebuilt several times before its final incarnation in 210, was completely demolished in 1549 and its marble re-used in churches and papal palaces. But the section standing today was reconstructed in the 1930s.
NOTES: The church was founded in the 9th century, its apse partly built into the ruins of Hadrian's Temple of Venus and Rome to the east. The campanile was built in the 12th century when the church was enlarged. The late Renaissance facade dates from 1615 by Carlo Lambardi.
