About this tour

You'll navigate Renaissance frescoes, baroque chapels, and the burial chambers beneath Christendom's grandest church.

What to expect
You'll start on the basilica's main floor, guided through its vast nave and chapels while your guide points out artistic and structural landmarks. Expect crowds, especially midday. The second half takes you below ground into the Grottoes—a cooler, quieter realm of stone corridors lined with tombs of popes and cardinals. Low ceilings in places mean ducking occasionally. The underground section feels more intimate and contemplative than the grand basilica above. Bring water; there's no refreshment inside.
Good to know
Modest dress required (shoulders covered, knees covered). Comfortable shoes essential for uneven underground surfaces. The tour does not include skip-the-line access, so arrive early to clear security. The dome ascent is separate and not included.
