What is the diameter and height of the Pantheon’s rotunda?

The Pantheon in Rome is renowned for its impressive architectural features, especially its massive rotunda. The correct diameter and height of the rotunda are both approximately 142 feet (or about 43.3 meters). This remarkable design creates a harmonious proportion between the height and the diameter, contributing to the sense of grandeur and space within the interior. The rotunda's elevation provides a stunning circular space topped with a coffered dome that is equally as impressive in diameter, emphasizing the ancient Roman's mastery of concrete construction and architectural innovation.

The choice of 142 feet for both dimensions reflects the Pantheon's identity as a temple dedicated to the gods, showcasing the importance of symmetry and proportion in Roman architecture. It is a significant element of the structure and has influenced numerous buildings throughout history, solidifying its status in architectural study and appreciation. Thus, this measurement highlights not only the achievements in engineering of the time but also its lasting impact on future architectural designs.
