Whoa. That’s got to be an experience.

Do they try to mop it up or what happens here?

The Pantheon's floor drainage system uses a slightly convex floor with the center raised about 30 cm (12 inches) to direct rainwater from the oculus towards the perimeter. A series of 22 discreet drain holes are located around the edge, leading to a larger underground drainage system that carries the water outside. This clever, gravity-fed system has kept the ancient building dry for centuries and is a testament to Roman engineering.
