Aerial footage shared by Unbranded – Lifestyle on MSN brings those different parts into a single view. The camera’s elevated position makes the relationship between the dome, the surrounding streets and the entrance easier to follow. At ground level, the columns and triangular pediment dominate the approach; from the air, the round structure behind them becomes the principal feature. That roof belongs to a building completed under Emperor Hadrian in the early second century AD. Its familiar outline is the result of several historical phases, from an earlier monument commissioned by Agrippa to its continuing use as a Christian church, covered in our account of [the Pantheon’s longer history](https://romanempiretimes.com/unveiling-the-eternal-things-about-the-pantheon-you-did-not-know/).

A complete sphere of that diameter would fit within the room, with its lower half occupying the cylindrical space beneath the vault. This geometry joins two simple forms: a cylinder below and a hemisphere above. The dome begins halfway up the interior’s total height. Its immense circular span rests on the thick wall of the rotunda, which the monument’s state custodians describe as more than six metres thick. The entrance offers a different architectural language. A rectangular portico, or columned porch, stands before the circular room. In antiquity, an enclosed forecourt directed visitors towards this conventional temple front, screening much of the rotunda and reserving the domed interior for the moment they entered. ## Agrippa’s name on Hadrian’s building The inscription across the front identifies Marcus Agrippa, son of Lucius, and his third consulship. Agrippa commissioned the original Pantheon in the late first century BC, during Augustus’s rule. The dedication therefore preserves the memory of the earlier foundation on the site. Agrippa was a close associate and son-in-law of Augustus, with an important role in the transformation of Rome. The original Pantheon belongs to that Augustan setting; our profile of [Marcus Agrippa’s early career](https://romanempiretimes.com/marcus-agrippa-the-napoleon-of-ancient-rome/) follows his rise alongside the future emperor. Fire and rebuilding separate that foundation from the surviving monument. The present Pantheon was completed under Hadrian, who retained Agrippa’s name on its façade. Its second-century dome and rotunda thus stand behind a dedication looking back to the building’s Augustan predecessor, rather than naming the emperor responsible for its completion. ![The Pantheon’s broad stepped dome rises behind terracotta rooftops and rooftop gardens in Rome.](https://storage.ghost.io/c/aa/80/aa80281a-abce-4f35-865f-05153c8cc335/content/images/2026/10/pantheon-dome-above-rome-rooftops.jpg) The Pantheon’s dome rises above neighbouring rooftops.

Cropped and rotated by Blackcat. ## The engineering beneath the roof The rotunda combines concrete construction with brick facing, visible on its exterior. That combination belongs to the wider story of [the bricks used in Roman construction](https://romanempiretimes.com/forget-concrete-the-bricks-that-built-ancient-rome/): the building’s curved form depended on concrete, while brick formed part of its substantial supporting fabric. The builders reduced the load towards the crown by making the dome progressively thinner and using lighter aggregate higher up. Porous pumice was incorporated near the top. The materials were therefore selected according to their position within the structure, reducing the weight carried by the walls below. Inside, the dome is patterned with five rings of recessed panels called coffers, with 28 in each ring. Together they make 140 panels, arranged around the central opening. Their repeated pattern gives the interior a different appearance from the broad, stepped outline visible outside. ## The oculus brings the sky indoors At the dome’s summit, the oculus is an opening directly to the sky. From above it appears as a dark circle; from inside it admits a strong beam of sunlight. As the sun’s position changes, the illuminated patch travels across the building’s curved interior. Research into that movement shows how the light follows a seasonal pattern. At the equinoxes, the midday beam reaches the junction between dome and drum; in winter it falls higher on the vault. During the warmer months, sunlight reaches further down into the room and across its floor. Rain also enters through the opening. Drainage holes in the floor carry the water away, making the pavement part of the building’s practical response to an open roof. The oculus links the external view of the monument to the changing conditions experienced by people standing beneath it. ## A Roman monument still in use The Pantheon became the church of Santa Maria ad Martyres in the early seventh century. Its conversion helped preserve a building that continued to have a religious purpose, while so many ancient monuments lost their original functions and were stripped of useful materials. Later generations added further associations. Raphael’s tomb is inside, along with the tombs of Italian monarchs Vittorio Emanuele II and Umberto I and Queen Margherita. Visitors therefore encounter Roman architecture alongside a much later history of religious worship, artistic commemoration and national remembrance. The building remains an active basilica today, with worship and visitor access sharing the same interior. Above that changing use, the dome retains the circular geometry visible in the aerial footage: a Roman architectural space still experienced beneath the opening to the sky. #### ****🏛️ Sources used:** [Unbranded – Lifestyle, “Aerial views of Rome’s Pantheon showcase the beauty of this ancient marvel,” MSN video.](https://www.msn.com/en-us/news/other/aerial-views-of-romes-pantheon-showcase-the-beauty-of-this-ancient-marvel/vi-AA2fW4Sf?ref=romanempiretimes.com) [Ministero della Cultura, Direzione Musei nazionali della città di Roma, “Pantheon and Basilica of Santa Maria ad Martyres.”](https://direzionemuseiroma.cultura.gov.it/en/pantheon/?ref=romanempiretimes.com) [Robert Hannah and Giulio Magli, “The role of the sun in the Pantheon’s design and meaning,” Numen 58.4 (2011), 486–513; author manuscript, arXiv:0910.0128v2.](https://arxiv.org/abs/0910.0128?ref=romanempiretimes.com) [Diana E.
