🏛 A Myth tells that Oculus of the Roman Pantheon, sacred place to all gods, was built so that rain could not get in. This is not 100% true, when it rains, it also rains in the Pantheon (a little less for the convection flow of air, a little less but it rains); the floor is slightly convex so the water flows away thanks to an effective drainage system! ⛆🏛 ⛆
