The Pantheon, one of the greatest engineering feats, was built in the time of Hadrian, the emperor known for his famous wall among other things, around 125 AD. This marvellous edifice has stood the test of time. While other monuments of the world crumbled, the Pantheon stands intact today, thanks to the brilliant design and engineering expertise of those responsible for this strikingly magnificent monument.
Structurally the Pantheon has an imposing entrance, constructed in the shape of a rectangle. The classic Greek influence is evident in the granite pillars that bear a triangular pediment. The entrance leads into a rotunda, topped by a dome. The entrance to the circular space has three rows of Corinthian pillars. Of these, eight are constructed in front, followed by eight more in two sets. This majestic rectangular entrance takes you into the rotunda.
That the circular structure should be able to hold up a 142-foot diameter dome for so many centuries stands as proof of the sound architectural knowledge, the combination of materials used and the precision to which the construction was carried out. At the centre of the dome is an opening called the oculus. This...
