Rome and it’s Basilicas
As I have said, Rome is a city where every corner tells a story. Comparatively to the Colosseum or the Pantheon, basilicas carry another dimension: spirituality. As an illustration, pilgrims from across the world don’t just come here for sightseeing, but because the basilicas are milestones in Christian history.
Why visit a Basilica in Rome as a Traveler?
Because each basilica in Rome holds masterpieces by Bernini, Michelangelo, Borromini, and Raphael, they are not just religious spots but also open-air museums. Besides, their atmosphere provides a rare silence in the otherwise buzzing city.
How many Churches and Basilicas does Rome have?
Rome counts around 900 churches and more than 60 basilicas. Although this may be true that you can’t visit them all, another key point is that each one hides unique treasures. From world-famous sites like St. Peter’s to small chapels tucked in alleyways, every Basilica in Rome has its own story to tell.

Instagrammable Churches in Rome with mirrors and frescoes
Where can I find the churches in Rome with mirrors to admire their ceilings?
Although this may be true that many basilicas impress with grandeur, another key point is that a few churches in Rome offer something unique: mirrors placed inside so visitors can admire Baroque frescoes without straining their necks. Consequently, these hidden gems have become must-sees for travelers looking for beauty and originality.

1. Church of Sant’Ignazio di Loyola – The Illusion of Infinity
Although this may be true that not every church is a basilica, this one deserves mention. Its ceiling by Pozzo creates the illusion of a soaring dome, although there isn’t one. As a result, mirrors are provided to enjoy it comfortably.
2. Church of Jesus – The Triumph of the Name of Jesus
As has been noted, Baciccio’s fresco is a baroque explosion of light and angels. Another key point: tourists gather under the mirror placed inside to photograph it for Instagram.
3. Basilica of Sant’Andrea della Valle – A Ceiling of Wonders
As soon as you enter, your gaze is drawn upward. Comparatively to Sistine Chapel, the dome fresco by Lanfranco is equally dramatic. Tourists often use mirrors placed inside to admire it without neck strain.
