The remains of the ancient town can be visited
Regia

The Regia, a structure in ancient Rome, is situated on the eastern side of the Roman Forum, near the Temple of Vesta. Originally serving the Roman kings, it later evolved into a location for religious and administrative functions.
Following the end of the monarchy around 509 BC, the Regia became the official seat of the Rex sacrorum, who took over the kings' cultic duties. Later, it served as the residence of the Pontifex Maximus and as a meeting place for the College of Pontiffs. The visible remains today stem from a restoration in 36 BC, indicating a presumed five-sided building. The Regia burned down multiple times but was always rebuilt true to its original form.
