Trastevere is often described as a place “with character”: narrow alleys, worn stone, squares where evening seems to arrive early. Yet if you cross it with a slow pace and a trained eye, it also becomes an ideal threshold for reading Baroque Rome not as a sequence of isolated masterpieces, but as an urban theater: a system of backdrops, perspectives, and surprises that rises from the banks of the Tiber to the Janiculum and then reopens the city toward its great monumental axes. It’s an itinerary that holds together layers—from ancient Rome to modern transformations—and restores the deeper meaning of Rome’s neighborhoods: distinct worlds that dialogue through details, silences, and sudden architectural epiphanies.
