Every year, for just a few minutes, something incredible happens inside the Pantheon.
The light coming through the oculus aligns perfectly with the arch above the entrance, forming a glowing arch of light.
These light effects were designed to show the emperor’s power, as if he could command even the sun itself.
Seeing this in person feels like pure magic ✨
Save the dates: this phenomenon happens only a few days each year, on April 6, 7, 8 and September 4, 5, 6, and only for a few minutes around 1 PM.
Here’s a closer look at this surprising effect.
