This is a famous etching by Becchetti of the Roman Forum, showing the circular Temple of Vesta
Here, you can get a sense of the position of the Temple of Vesta sort of tucked between the Temple of Julius Caesar (the temple built after Caesar’s death, to mark the site of his funeral pyre) and the temple of Castor and Pollux. On the right and moving upward, you can see the Palatine Hill, where the emperors had their homes.
