Yes, this is the Bishop of Rome’s church. And who is the Bishop of Rome? The Pope, of course. This is where he gives sermons on the most important catholic holidays days. The second most important church in Rome, after San Pietro. And not too far from beautiful Santa Maria Maggiore. Fantastic mosaics, but most importantly – the ORIGINAL DOORS OF THE ROMAN SENATE, we are talking 2000 years+… Do not wear shorts (man or woman), they won’t let you enter. Lovely cloister and Roman artifacts museum (€4 admission charge). Convenient taxi stand right in front, Piazza di San Giovanni in Laterano.
