It is a Renaissance style church built between 1506 and 1626. And it is the church of the Bishop of Rome (The pope).

I also have some videos for you at the bottom of the page.

This first picture is a view of the basilica as seen beyond the Bridge of Angels.

This next picture shows the Baldachin inside the Basilica. It is a baroque style structure over the altar. And it was designed by Bernini. I have a video about Bernini below. He is not as famous as Michelangelo or DaVinci but he should be. He wasn't a Renaissance Artist. He came shortly after they did and he ushered in the Baroque era.
