Santo Stefano Rotondo

Santo Stefano Rotondo is one of Rome's most unusual churches because its circular plan makes the space feel unlike the city's better-known basilicas. The site sits quietly on the Celio, close to the Colosseum, but it often feels almost empty compared with the major attractions nearby. That makes it especially good for travelers who want a calm, early-Christian interior and a break from crowds. The building's age and form are the main reasons to come; the atmosphere is the bonus.
