Day-09 Our day for Pantheon , We were there for half of a day and thus decided to visit Pantheon, last day for using Rome Train pass and our destination was for Piazza della Rotonda, the closest to Pantheon. The Pantheon is a former Roman temple, now a church,and the best preserved Ancient Roman monument.Probably one of the most fascinating features of the Pantheon is the Architecture. The structure of the Pantheon is comprised of a series of intersecting arches. The arches rest on eight piers which support eight round-headed arches run through the drum from its inner to its outer face.The dome itself is supported by a series of arches that run horizontally round. Romans had perfected the use of arches which helped sustain the weight of their magnanimous buildings.This use of lighter materials on top alleviated the immense weight of the dome.However, the Roman Pantheon in its present state allows us a glimpse into the marvelous and stunning world of Roman architecture.
